Why does it have to be like that?

Hi,

Well first things first, my computer is back, so I will keep you posted more often! Surprisingly enough this time the whole repair process took only a week! WOW! I am amazed!

So today I wanna talk about relationships. Lets look at friendship first. Whenever you have a friend, it is pretty cool to hang out with and you might invite other friends for it to be more fun. Or you might pick a new friend and your old friend will also become friends with the new friend. So basically you can have a lot of friends and everything is cool. Now lets look into dating and marriage. Surprisingly(for me) the same rules do not apply here, although the nature of the relationships is very similar! Having one girlfriend and picking up one more at the same time sounds like trouble and not something good to do! Now I wanna know why? Why is it ok to hang out with many people but not ok to kiss with many people? Please don't get me wrong, I do think, that one should only have one girlfriend at a time, but I don't understand, why? Why does it have to be like that?

Your suggestions are very welcome!
