Last Friday I really hit it off with a coworker after our office went to a bar together. There was some physical contact, and we ended up leaving together, but I dropped the ball and didn't ask to come up to her place when I dropped her off. I really want to keep talking to this chick, and planned to speak with her again that following Monday, but I haven't seen her since then, even though I know she's been around. We work in different parts of the building, and I've been super swamped with work, so I haven't gotten to leave my desk all week.

Anyway, I know for a fact that I'll see her on Monday again during a meeting. Have I waited too long to grab her number? It'll be over a week since we would have talked, and I was dying to grab it all this week, but the opportunity never came up.

Have I fucked this up beyond fixing? Or am I over-thinking this and should just go ahead and ask for it the next time I see her?
