So I met this girl at the bar last Thursday. I was kinda being a wallflower but she caught my eye so I nutted up and approached. She was really cool and we talked about various shit for a while. At one point this guy comes over and basically blocks me out, so I just leave to do my own thing.

After about an hour, I go back to the girl- she's still talking to the guy, and it looks like her friends are all trying to leave. I made a last-ditch effort and basically invited myself along with them to the little "after-party" they were going to. It was at her friend's place.

When we got there, I tried talking to the girl a bit but it seemed like things had fizzled out between us (even though the other guy wasn't there anymore). I didn't have any other friends there, so I just drank a bit more and watched some guys play Super Smash Brothers for a while.

Eventually I grabbed my balls and walked over to the girl. There was some small talk and I just asked for her number. She gave it to me, but then when I tried texting yesterday, she didn't respond. I don't know what to do now.

So... tell me every single thing that went wrong. This wasn't a real interaction, but it's pretty damn similar to a lot of situations I've been in before. I want you to come up with as many ideas as you can. Just glancing over it, I can name 20 things I did wrong. Let's see who can point out more than 20 (and make sure you give a reason for each).
