Senior Year of College

[ryanrabl]

It's my senior year in college and I'm almost finished with my major,thus, I have a little more time to go out and socialize.In the past 3 weeks,I have ran into a girl at 3 separate parties.When we first met,we had a short conversation and there was some sort of chemistry,but I brushed it off and thought I would never see her again.A week later,she approached me at a mutual friend's party where we spoke again (slightly inebriated) and I got her number.I saw her last week for the third time (this time sober) and had a short chat (she had to go early because she had work in the morning).Last night,I ran into her and her roommates at a social gathering at school,they (her roommates) wanted to leave, but she decided to stay back and talk to me.We ended up talking for a good 4 hours!I never have really long conversations,but we quite literally spoke about the most random things .So is that a good sign?Im thinking of asking her out to coffee sometime this week..keeping it informal and short.What should I do?
