The point of all this "wait to call or txt message" stuff is just to show you got a life going for you and you're not desperate. For some reason people on this board take it to the extreme and think you got to keep playing "busy" and "hard to get" ALL THE TIME...OVER EVERY STUPID INSIGNIFICANT THING. They analyze every damn communication with a girl to death, and then beat the living crap out of it while it is dead.
ffs, you just had a date with her and she messages, you, she KNOWS you're not busy because you just got off a date with her. It's not likely you're already well into some work or something.
The main point of waiting to call or message a girl (not showing desperation) is to:
1) Get that initial date.
2) Not mess it up by calling her every day after the date.
She's not going to be more attracted to you for waiting 1 hour to txt her back after the date. If anything it may have the opposite affect by showing you don't care or aren't interested. Notice, she is NOT thinking "Oh this guy must be busy 1 hour after the date because he didn't txt me back. I'm getting so horny for him now since he didn't reply for an hour. In fact, I think I'll sleep with him tomorrow." Do you honestly think something that ridiculous is going on in her head. Just txt her back ffs!
