I agree to a point. Long telephone conversations are pathways to the world of LJBF. Basically they spend a ton of time with you on the phone when they have nothing better to do and if they are very talkative.
What I do is talk to them for a few minutes (usually no more than 5) about BS, nothing heavy or serious. Just yesterday a woman called me at work to chat. I basically just talked about that new game Fable on XBox that I'm playing.
I told her about my character and a few of the adventures I had completed. Yeah, I know it sounds geeky but I tell very colorful and exciting stories. Anyway she asked if she could come over after work and watch me play.
I was game, so I told her to pick up some things from the grocery store and that she could help me cook something for dinner, she was pleasantly surprised at the suggestion and was all for it. If you guys haven't tried this before it's like money in the bank!
Anyway, she came over, she watched me play the game for a while, we cooked dinner and then we
really played and cooked.
All I'm trying to say is that telephone conversations are good if you keep the woman a little off balance and try your best to surprise her by being unpredictable.
