How Long?

I am sitting here on the couch watching "Joey" with Chris. The premise of the show is that Joey's nephew has moved in with him & is looking for dating advice. The nephew finally gets a girls number and there is a debate on how long to wait to call someone. Well, I am going to clear up the confusion for all of you men out there, and for the women who expect a call that night (ridiculous) and the ones who think three weeks later is acceptable.
Situation One:
You are at a party/bar/club/church/restaurant. An unknown approaches you. You talk, have great banter and he asks for your phone number.
If he doesn't call within three days, forget it. It's not happening. If he calls next week, blow him off. He was obviously not that interested and you should not be either.
Situation Two:
A friend introduces you to someone. Because you share a mutual friend, there should be some sort of communication within 24-48 hours, even if to say "It was nice meeting you, but..." (you don't want to make your friend have to explain to the other friend that there was no chemistry, be man, or woman enough to do this yourself, and quickly)
Situation Three:
You go on a date, expect a call within 48 hours (I believe 72 Hours is too long). If the date was terrible, guys, call and break it off the next day. Don't put off what you can do today for tomorrow. Fish or cut bait, one of my FAVORITE sayings when it comes to relationships. If it was great, why would you want to wait? Call her in the mid afternoon to let her know you enjoyed yourself.
RECAP:
Women don't want someone who is overly bearing. A call that night, or even the next morning may seem to be a bit too eager for a woman, and it can turn us off. HOWEVER, if you are overly aloof, we may think you are stuck on yourself, disinterested, or just a complete jackhole.
Take your time, but hurry up!
