There's this girl that I work with that seems to be interested in me. She's usually tracking me down to talk, playfully hitting me, and otherwise testing to see if I'm interested (she's a 7, but kinda taller that me). Well, I've thought of asking her out casually since I'm not after a relationship with her and would only be after sex (that's because she's moving in a couple months). I've thought of maybe just asking her if she wants to grab a beer after work, but since I work with her I don't want things to be obvious (especially to our coworkers, because for one I work with quite a number of cute girls). So, do you guys got any good ideas?
