My friend's brother...

He's so fricken HOT!! And he's funny and he has perfect hair and teeth and he's just beautiful and he plays piano (I do too) and he's nice and he just... idk... I like him a lot. I DONT want his sister to think that I'm only her friend to get to her brother. NOBODY knows I like him yet.

2: Should I tell him?
3: don't tell anyone because it will ruin our friendship 
4: stop worrying
