I casually mention something I would love to do. For example, “I really want to see XYZ movie!” or “I’ve always wanted to try ABC restaurant!”
You’d think it was that easy, but no chance, because girls with boyfriends also like to go to see XYZ movie or try ABC restaurant, and they also like to tell us.
We still don’t know shit!
Simple answer: once girls enter a relationship they are no longer allowed to like things. That way, when a girl says she likes something, we know she’s single! It’s foolproof!
Subtle touches on the arm. Seriously, if I don’t like you I’m not gonna actively touch you.
If I am looking you in the eyes and smiling a lot, I am interested.
If I am unable to hold a conversation like a normal human being, but keep asking you dumb questions, it is because I am VERY interested and therefore unbelievable nervous. (Just give me a little time/a few drinks and it will get better).
