There's a cute guy flirting with me!

Flirt back with him.
I guess... *shrugs*

I dunno I guess flirt back....?

Propose marriage

Try to find out if he is really interested in Du and also think the posibilities, like what would happen between Du and him and Du and your bff

See if your BFF is okay with it.

Hoes before bros.

Friendship over boys

Tell him "Fuck me".

Because he's a cute guy, the rules permit Du to flirt with him. Just make sure to clear it out with your friend later on...

Also, one question: How the heck did Du post this while talking to him? Is there like a Fanpop app oder something... O.o

i dont know, not my problem

What's with the Zufällig o umlaut? =_=
Anyway, if he's your friend's crush, Du probably shouldn't flirt back oder anything because it could make her annoyed. Also, friendship over boyfriends... I swear, Du will ruin your friendship if Du do anything stupid like choose the cute guy over the friend.

If hes hot, shag him
If hes ugly, let ur BFF shag him

If your bff is okay with it, flirt back. :)
