Why People Shouldn't Be Impulsive

I learn something new every day. Two days ago I learned that my Chemistry teacher takes out his anger in the form of impossible tests. Yesterday I learned that a gladiator can, in fact, escape fom slavery with nothing but kitchen utinsels. Today I learned that Cory should NEVER EVER, under any circumstances, speak until she has considered her words for longer than half a nano second. EVER.
I won't go into the details, because it sucks to have your mistakes displayed out to the whole world, but suffice it to say that this is a problem that I fully intend on fixing. And it isn't just today. I've never been able to keep my fat mouth shut. They'd never tell me, but I'm almost 100% positive that all f my friends have been hurt by something I said, not realizing that I was hurting them.
Sorry guys. My bad.
