actually, and I have had to make this dicision a number of times, if you ARE actually a very busy person, and you meet a girl you like, your damned if you do and damned if you don't.
You can't ask for her number and not call her because she will likely spit in your face when she sees you.
You can't NOT ask for her number because she will then put you in the Friends Catogory.
I have had both happen, more than once. It's one thing to "make yourself busy" but when you work 6 days a week for 14-15 hours a day, have family obligations and your own hobbies that you either want to decicate time to or at least take seriously enough not to miss them, not to mention actually friends, it is IMPOSSIBLE at times to meet new people.
