do I have bad chat breath?

Do you ever have those people that are in your buddy list
that you only occasionally chat with,
and when you do, you exchange about 3 sentences,
before they suddenly have to go?

And you think,
"was it something I said?"
or
"am I annoying?"

So just in case I've ever been that person to any of you, I promise if I "have to go" I really do have to go, and don't take it personally. Pinky swear!
