<human>: Can you provide a brief overview of the text?

I don't normally experience much anxiety over asking girls for their number or asking for dates in most social sitations. However, I'm willing to admit that I'm having a little difficulty with asking a female co-worker for her number.

A little context: I'm fairly new at this job (less than 2 months) and this girl has caught my eye. I chat with this girl whenever I have the opportunity, and she seems pretty receptive. A different co-worker had a birthday party at a bar close by, and the girl I'm interested in showed up. This was my first opportunity to talk with her outside of the office. We seem to have a lot of common interests, she even offered me a taste of her beer (without my asking), she would make certain physical contact during conversation (hands on back of shoulder, for example). I even brought up the idea that we should go skiiing sometime (were both avid skiiers/snowboarders), to which she responded positively. Only other signal is that at the end of the night she didn't make a point to hug me and say goodbye, though she was a willing recipient when I came in for the goodbye hug (lol). One last crucial bit, due to business needs I won't be working at her location for a few weeks and thus, no in-person opportunities to strike up more conversation.

To wrap this up, at the end of the night I failed to ask for her number. In retrospect, this was a perfect opportunity that I completely missed. I'm having trouble with this because, in most scenarios, if the girl rejects me I can just move on and forget about it, no harm done. But in this instance, I have to see her everyday (typically). Any tips about how I might handle this with some level of class and tact?
<bot>: Interested in girl at office. Having trouble asking for number/date in a way that won't make things weird.
