Why do people do this?...

Why do people feel like they need to have sex just to prove they're in love? Now I have two friends that are pregnant, well the other was pregnant but that's another story maybe for another time. I don't know, I just don't get it I guess...

And on another note, why do sisters or supposedly sisters like to do what they do? Family issues can be quite annoying, aggravating, complicated, sometimes radical, and any other name you can think of. But I have to shake it off and release all of this pressure and get over it. That's the only think I really can do, otherwise I will be torturing myself and putting myself through excile and that's not going to happen. I won't let any of this affect me or put me down. I'm stronger than that.
