Promised myself I wouldn't talk to no more girls at work buuuut there's this new girl 18 years old, cute face, slim waist, and packing a nice ass and she's into me. We made eye contact a few times, had small talk and playful banter, I compliment her and she laughs and giggles. So all of this is a good sign, only problem is that I don't know if I should ask for her number out of the blue. We work different departments and I'm always busy. All I could say is good morning with like 30 seconds of small talk before she has to go back to work. Do I just say "hey can I have your number?" Wothout building up to it? Or is that too direct?
