Waiting the "obligatory" three days
Even though you want to phone her the next day, you don't want to seem desperate, so you follow the golden rule of waiting three days to call her. This is predictable; she'll see right through it.
What to do instead: Surprise her by calling her the next evening. Believe me, if she's into you, she'll be happy you did.
I've never got this "rule." Do girls actually respect a guy who is trying to prove he doesn't care that much about her? I don't usually have much of a plan when it comes to these things. I don't have a girlfriend, so I guess that I could be doing it wrong. I have always called as soon as I wanted to talk to her again. Usually, if it's someone that interests me, that is the next time I have an 45 minutes to an hour of uninteruppted time to devote.
Does anyone out there still follow the three day "rule"? Does anyone who follows it still follow it after seeing Swingers satirically mocking the rule? On the other side, do girls like a guy who doesn't call them for three or more days?
