Yesterday my "friend" come to me with his new (not so new, honestly) girlfriend and I think she was interested in some way in me.
There's not much to tell, long handshaking, some sort of eyes game, but, uh, It was strange sings of attention, I'm not sure in her and her plays.. Although i liked it.

She is calculating your net gross
Even if she did like you, don't even think about it. That's your friend's girlfriend. She is off limits.
