Now here is the thing, yesterday I went to a Christmas dinner from our school faculty. She also was there, but we didn't really had the chance to talk to eachother, we made eye contact and smiled to eachother a couple of times though. Now, since next week is gonna be the last time I'll see her in quite some time (it is the last week of school before the holiday and the exam period will start), I was meaning to ask her out last evening. But because she was always with her friends or working at the Christmas dinner, I let the chance to ask her out slide.
Now I am a bit bummed out about this, and I was wondering wether or not it is a good idea to ask her on facebook if she wants to go to the local Christmas market with me on Friday evening this week.
But is this appropriate? I really wanted to ask her out last night but it just didn't happened, and I don't want to wait till February to talk to her again. However I'm afraid she will find me daft for not asking her in person at the Christmas dinner. What should I do?
