3) Getting A Phone Number correct answer = b
Whilst there is never a hard nor fast rule for any of these things, clearly a woman wants a man to be confident and the more he 'expects' to get what he wants the more he probably will. Asking to go out on a date will often be too specific and frightening for her. Giving her your number and waiting for her to call you is usually a waste of time, and is out of your control. Casual is cool, so ask for her number, and expect her to give it to you while you chat about some other thing, or don't bring too much attention to it. Put her at ease so nothing is ever a big deal.
