Input: Text: so basically me and my best friend are just chilling in town watching people walk by and shit, until this super hot chick with a big booty walks by. i stare and excitedly tell him to look that way pointing in her direction asking him if i should walk up to her. he looks at me disgustingly, making awkward eye contact, saying that she's his sister. 

i simply get up, and walk away. 

i now know i lost my best friend.

TIFU by checking out my former best friend's sister.
