Me in my grandparents house's bathroom- *finds a weird handprint on the mirror & instantly puts my hand over it to see if my hand is smaller or not*

Twin- Wow... you just did that without hesitation...

Me- Yeah? What else am I supposed to do?

Twin- Oh I don't know, maybe not put your hand on the weird fucking handprints?!

Me- *shrugs and walks out*

(Just so u know we were both brushing our teeth & that's why we were in the room at the same time)
