okay, so a fact is a statement that is confirmed to be true, like two plus two is four. An opinion, like this one about you being far from neat, can't be confirmed, because both sides in an argument with this topic both have excellent points and can only be decided on the person's opinion. Like, some people think you're a complete jerk, and others think you're a decent person. It all depends on how you look at things.
I think I sound like a nerd.
