Sherlock-
It was a chilly London afternoon and you were oddly happy at the fact that you had managed to drag Sherlock to a café. You know that he doesn't really like to socialise in public places but you put on your whiney 'do it for me' eyes and he reluctantly agreed. After you had both finished your ludicrously overpriced coffee, Sherlock reached his lanky arm across to another empty table and grabbed a newspaper. Immediately, he flicked over to the very back page and giggled to himself
"Oh, I do love these... Whoever makes these quizzes must be an absolute moron. These questions are painfully obvious I bet even Lestrade could answer them."
He looked up at you and giggled even more as he read out one of the questions...
"What is the formula of an ammonium ion?"
Just then, your expression went blank and your giggling ceased. Slowly, your brow dropped and you thought hard about the answer but to no avail... You didn't now.
"Umm... Ask another" you said timidly as Sherlock's expression also changed to one of an apologetic nature.
"Umm... Ok, what is the relative atomic mass of oxygen?..."
Your expression slowly crumpled from blank to teary and you hid your face with a napkin in an attempt to shade the tears which were welling in your eyes.
"I'm stupid.... I'm a complete idiot..." You whispered through the thin tissue until you felt Sherlock warm hands grasp your own and stroke them comfortingly.
"(Y/n) you aren't stupid..."
"You just said those questions were easy! I didn't know any of them!"
Sherlock stared into your cold eyes and reached forward to brush a tear from your cheek.
"No" he stated plainly "(y/n), I have one of the highest or possibly the highest IQ in the country. I am extremely intelligent. Just because you don't know everything I know doesn't make you stupid... It makes you human. Something that I rarely feel..." He squeezed your hands harder and sighed
"You can't put yourself down for not knowing a few difficult questions, that's absurd... Please, have some confidence in your intelligence... For me"
You were back to smiling now, tears all but gone. You grinned at him as he took you by the hand and lead you out of the café and walked, arm in arm, down the crisp, empty London street back home.

John-
When you are around John, nothing else really matters. He is what completes you, he makes you whole and loves every single bit of you. That is why, if you ever dare criticise yourself or put yourself down when he is around you, he will do everything in his power to make you feel better about yourself. To be honest, you don't do it a great deal, you don't have many flaws, your personality is amazing -yes you have some body issues now and then but who doesn't?- but there is one thing that just keeps annoying you every single day. Your height...
It was yours and John's movie night and almost everything was set up. Caramel popcorn on the table, enough blanket to sink a ship, lights turned down with a rose candle lit and flickering calmly on the mantelpiece. You just had to decide on the film.
"Joooohn" you cooed while exercising your puppy dog eyes technique "can we watch love actually?... Pretty please?.." He pondered your suggestion before sweetly agreeing and kissing you softly on the forehead.
"Ok babe, you get the film and I'll turn on the TV" he smiled as he rose and meandered across to the DVD player where he began to methodically fiddle with buttons. As he did so, you were trying to reach for the movie off the shelf but failing miserably. Being only 4"11, reaching high objects really annoyed you and eventually you gave up, a slight ghost of a tear beginning to form in your eye. Immediately noticing this, John got up and approached you quickly, engulfing you in a caring hug. This however, only made you cry more...
"Why do I have to be so short John?! It's not fair! I want to be tall and elegant like other girls but instead in a little stocky thing who needs help to reach a DVD off the bloody shelf!" As you spoke, you let out an eruption of falling tears and uneven gasps of emotion which merely made John hug tighter.
"Now sweetie, just stop for a second and listen... Being short doesn't mean you aren't elegant, being short doesn't mean you are stocky, being short doesn't mean you are any less important than anyone else on this planet. You are beautiful and I love you. Heck! I even have to ask Sherlock to reach things off shelves for me at the yard because, let's face it, I'm no giant either."
His emotional speech made your heart warm a little and the corners of your mouth turned up to form an unavoidable smile.
"You done putting yourself down?" He asked intently. You offered a simple nod in response which appeared to be enough to fit his need. "Good".

Mycroft-
It is no secret that Mycroft loves to spoil you. So much so in fact, that you never go without anything. Ever. One of his favourite activities is to take you shopping, not just because he is rich and can afford beautiful things, but because he always strives to show you how much passion and love he has for you.
"Ooooh. I like this one" you stared in awe at a pink and black cocktail dress which was embroidered with hundreds of little lace flowers cascading down the bodice. You picked it off the rack and twirled round with it, giggling as Mycroft looked on awkwardly (he didn't enjoy making a scene). You put the dress back considerably quickly after pondering the price tag and took Mycroft by the arm and dragged him out of the shop with you. After you had explored a few more shops, Mycroft pointed out one particular dress in the window across from you. It glistened with angelic elegance and Mycroft smiled as he saw your eyes illuminate suddenly.
"Want to try it on?" He asked you cheekily. You couldn't answer, all you did was nod wearily as he ushered you into the shop. Ten minutes later, you had located the dress from the appropriate rail and were stood, surrounded by mirrors, in the unflattering glare of the changing room. It was the kind of light which would only look good if you worked for Victoria's Secret. Nervously, you poked your head round the door and bit your lip.
"The dress is gorgeous babe... I just don't think it looks good on me..." You pulled back the door fully to display yourself in front of him.
"It makes me look frumpy. I think this dress was designed for thin women... Now women like me..." Mycroft was absolutely taken aback by your comment. He was actually rendered speechless for a few moments before finally retorting
"Precious? Where did that come from? You are thin, what do you mean?" You looked him up and down before sighing and folding your arms over your flat stomach. Mycroft noticed this and continued his explanation "(y/n). I will not stand for this self deprecation, you are nowhere near fat and you should take that from me, I know what fat looks like... Please, precious. Don't put yourself down"
You rotated back around to stare into the mirror once again. 'Huh...' You thought silently to yourself, maybe it's not as bad as I thought? You turned back to Mycroft once again and approached him with open arms
"Thank you Mycroft... Thank you"

Greg-
It had been three years. Three long, tiring years since you had taken that low paid internship at the yard where Greg worked. So far, apart from an apparent lack of sleep, you had absolutely sod all to say for it. One day, you just broke, enough was enough...
"Greg?" You said quietly as you knocked on his office door with one knuckle. You entered slowly after straightening your uniform and stroking your hair back into a sleep ponytail to appear more sophisticated.
"Yes babe" Greg replied with an unaware smile, not knowing what you were about to confront him about. Taking a deep breath of coffee scented air, you began to speak.
"Am I good at my job?" You asked plainly.
"What?" Greg responded, confused.
"I've been here for three years... No promotion, no pay rise, no congratulations, no acknowledgement of what I do... I feel like a failure. I've let myself and you down... I'm sorry" Greg was astounded by your concern and rose from God desk, a solemn look on his face.
"(Y/n), this is an incredibly hard profession. You know how long it took me to become an inspector? 10 years... I've done this for 10 years. I've fought and struggled just like you are doing now. You aren't doing anything wrong. It's the hard way but it's the right way..." The caring and truthful look behind Greg's eyes filled you with determination and you wrapped your arms around his neck, kissing him as you did so.
"No more self deprecating are we clear?" Greg said, smiling as he returned to his chair at his desk.
"Ok Greg. Love youuu" you grinned cheekily as you left the room, filled exponentially with confidence.
