1. Stay the hell away from me.
2. Ummmm...whatever.
3. Cry about it.
4. No one cares.
5. Go suck one.
6. I'm sorry to hear that but you don't see me caring.
7. THE SIMPLE ONE: I don't care.
8. Go away, I don't want to see you.

But if anyone said these things to me, I would kick their anus to the moon.

I'm a b**ch. =D

"So, uh, why're you telling me this?"
"That's a nice story."
"And now on to less irritating things."
"And this is why you can't have nice things."
etc.

I'm kind of a mean person. XD

"If you can do better, then go ahead and try for yourself."

Or various forms of it. It pisses me off when people who do it worse than I complain to me that I'm doing it wrong. Unless they're teaching me something. Not walking fast enough in a crowded, jam hallway is another story.

I use some of the ones you use, kind of. Well, for number eight that you said, about "I'm sorry, was I supposed to be listening?", instead, someone is sitting in front of me, and they just keep talking and after they're done after 5 or so minutes, I kind of "wake up" and say "I didn't listen to anything you just said *smiles". Another one I say is, I don't really care, go find someone who does, or something like that. Um...I have a bunch of others but I can't really think of all of them at this exact moment in time.

I like saying #'s 4, 8 and 5 to annoying people..
(Now you gave me ideas on what more to say to them. thanks! ^^)
I just really hate it when people are annoying.
Ughh.
