So I was in a hurry to an event today. I left my dorm but ran into this girl.

She goes "why are you always at 'dorm name'".

I go I am going somewhere right now or something.

She told me she came back from doing something for the crew or whatever.

We talked for like 20 seconds, maybe less. Then as she was talking I said "alright I will see you later." and gave her a weak hug, basicaly just touch her back with my hand, facing her and walked off, without looking at her face.

She said a weak "see you later."

I have no idea if that was good or bad. It kinda communicated disinterest?

Should I apologize about that? Go like "hey sorry about last time, I was in a hurry." on her facebook or next time in person?

NEVER facebook chat a girl you don't have really good rapport with.

Next time don't even mention it. If you give her attention next time, she will not hold it against you.

In fact, the image that you have better things to do than sit around and give her attention all day INCREASES your attractiveness in her eyes.

I've had two girls wanting to do me *purely* through facebook conversation. It doesn't make a difference.

But yeah, if you don't pay her any attention for a while and then eventually become more interested in her, it's far more attractive than being a kiss ass who remembers every conversation you've ever had.
