not and then she will be pleasantly surprised when you finally call her.

Always be honest and sincere on the phone, as it can be very easy to say a little lie when you don't see her. Don't overstate your personal qualities, interests or anything else - just be yourself! And it's her problem if she doesn't like smth about you; just don't waste your time on her.

Always respect her work or living schedule, and never call her at work (you can call only if she asked you about this).
