Looking to get opinions on a specific incidental encounter that happened last week.

Was at a bar solo and struck up a conversation with a girl. She didn't seem into within the first few minutes so I took a walk around started talking with some other groups. About thirty minutes later, my drink is empty so I go back to the bar where she is still sitting in the same place. I give her the old "Oh hey, you again." line and low and behold, her reaction is much friendly. We talk for about 15 minutes with lots of laughs and banter. Looking back on it, I should have gotten her number right then and there but, I didn't.

So here's my question. In the course of conversation, I mentioned that I live literally right next door. She was curious about this and started guessing what buildings. Then, she tells me she's at this bar "just about every Friday." If that's true, she knows I'm not there every Friday. If I show up again and talk with her for a second Friday in a row, is that going to come off as creepy?

Thoughts and opinions welcome. I realize I missed the initial opportunity but, want to redeem myself on the second go around.
