Lying!

Man i hate people who lie. They just don't and won't stop lying. They sound like Sean "P. Diddy" Combs when he says "Can't stop won't stop." All I'm just saying is that they need to stop. Whats going to happen when they get caught lying for something important? They are going to lose friends and even family. Nobody likes liars, or at least everybody i know don't. I just hate it when they lie about something small, that's what bugs me the most. For example, i asked my friend if he wanted to go do something and he said no cause he had to go somewhere but he didn't. Like how does it make you feel when you lie? that's what i want to know, and why do liars get so attached to lying? I need some answers.
