A hint to the riddle: it's what makes you live and feel happy but when betrayed it is just a...?

And now:
Victory, why so? Hmmmm... Well maybe it could be...
Praaaaaaaaaaaaaaaaaaaaank!!!!!! X'P
Last night there was this sleepover and well... Let me tell you all a little story.
It goes like this:

When the prey was dormant, the beast snuck up with a marker and a whipcream spary can.
It took awhile, as the prey tossed and turned in its sleep, but the beast managed. Then snuck away to hide any proof.

***

Next morning

*groan!* groans the prey waking up "aaaaaaaaaaaahhh!!! What the *biiip*!" She exclaims as you hear *sqush* sound bringing her hand full of whip cream up to her face to rub the sleep as her eyes. The beast roars in laughter as the prey attacks starting a war of pillows.
In the end the beast who was now the prey (or so she thought) calls for the white flag still snickering tears of laughing to hard in her eyes as the beasts creater yells for silence.
Then the prey leaves to clean up her cream smeared face laughing along only to yell when she sees her reflection in the mirror as she sees a mustache messily drawn on her face.
"Beeeeaaaast!" She shouts.

That's how my day started.
The beast was me, the prey my friend that slept over.
Ps
She was very suspicious when she saw breakfast.

Wonder why... XP!
Akray out!
