I do it because I cant stand having to go over the same shit time and time again. I could never teach kids, argueing with people like "frigginregan" is like teaching a three year old that 2 + 2 = 4. You know your right but they keep saying no it is 3. The only difference is, at least the three year old has little experience on this and I expect others here to already have some common sense about them.
