Leaving it out indicates you are aware one was needed. Since you don't know where it belongs, that means you're too stupid to know one was needed. BTW, you left out another one in this post, plus an apostrophe. Bet you can't tell us where they go this time either, imbecile.You were talking grammar and spelling. So what I left out a comma. Whats going to happen? You going to mark me down on my term paper?I wasn't talking "grammar", I was talking spelling but I guess an idiot like yourself wouldn't know the difference.Yes you are an idiot. Like I said it cracks me up when you start talking grammar. I know that means you have nothing left.Speaking of idiots, I like how you spelled the same word (you're) two different ways, both of them wrong.Idiots like you just make me laugh.Not mad, just annoyed. Idiots tend to do that.
Of course your mad. Youre like a monkey with rabies right now.
PS, you left out a comma (twice), think you can figure out where?
