3 Day Rule?

I don't think the 3 day rule exists in SF.  I met 2 guys at a party a couple of weeks ago and they both contacted me this week.  1 guy sent me a reminder that he exists.  The other guy actually invited me to do something.  I am going to take up the guy who invited me to do something.  He is the player type and semi-aggressive.  Good!

I wonder how much time they spent trying to figure out 1) when to contact me and 2) what to say.   It's possible that they have been thinking about it since I met them.  Haha.
