Okay, overall, you're not so bad, Mr. Gochiefs. The most important thing I can say is avoid that nerd talk. Some girls like nerdy guys. But that doesn't mean they want to talk about digital cameras and gmail. It means they think it's cute if you have glasses and are kind of skinny. If a girl really is a geek herself, you'll figure it out and you can talk about gmail to your little heart's content. Until then, just stop it.
Also, I'd probably avoid telling drunken stories right away -- although this girl didn't seem to mind it.
The other big thing here is that, while it wasn't really a BAD conversation, you didn't seem that interested in getting to know her. I think you ought to be asking more questions about her. Where's she from? What's her family like? What kind of music does she like (you kind of got into this a little bit)? What does she like to do for fun? Where does she work? Etc. Girls, in general, love to have a guy really talk to her and seem interested in getting to know more about her.
And don't forget to ask if she does anal.
