I met a guy at a school party and we talked for a bit few months ago. Now whenever he sees me at school he always says hi and he tried to talk to me once about school work. He is always well aware if I am around him. He also talked to me last week, and I was surprised that he remembered my name since we last met was few months ago and we only talked for a bit. Yesterday, I was at the library reading and when I looked up I noticed he was looking at me, so he waved and smiled and I waved back. Is he just an Outgoing guy?
