Social Hacking

I been thinking a little bit more about the unwritten rules that we humans follow (or don't follow). These rules differ between both different cultures and different sexes. I think that the cultural rules are easier to analyze and understand. However, the difference in rules between the sexes are more interesting to analyze. So I am going to do a little thinking about those differences in this post.
A few post back I was talking about a conversation that I heard on the bus and the mind games a girl was playing with this guy (boy/guy/man, girl/woman, late teens, early twenties). I call them games but according to the tone of her voice and the way she acted it seemed like something completely normal. The interesting part was that I don't know if she really liked the guy, however, the important part was to understand if he liked her.
So to accomplished this she apparently dumped him and expected him to come crawling back. This I personally don't understand at all. If I would get dumped by a girl I would respect her decision and not try anymore (is that wrong?). However, according to her rules, he should come back if he really liked her.
The other thing I clearly noticed was how important and obvious it was at what time he should call here. For example, if she called him and asked him for a dateish meeting but they did not agree on a time, he was supposed to call here back the next day before noon. Since otherwise he did not want to meet here. Another example was when he called her just to talk one day, if he did the same thing withing 5 hours again he was desperate.
I have tried to understand these thing and given up. Anyone who wants to explain?

I just have to add that I am not writing my blog to judge people or to make you think the way I think. I only write this blog because I think this subject is really interesting. I enjoy sharing my though and I really enjoy discussing things like this with other people. If I offend anyone, please tell me..

I got a sticker on my laptop that advertises this blog. I have gotten a few questioning looks today. I like it. (thought about making a smiley.. but naah..)
