I make myself laugh

A conversation I had with my brother yesterday over IM:

brother: I have a $100 bet with cousin Cameron on who will get the better GPA this semester. He picks 2 classes...to go against my two classes.

me: haha

tell him he should come visit us?

i didn't need a ? at the end of that, did i?

brother: Did you?

me: no?

i don't think so?

i don't know?

brother: Do you want to play questions?

me: i hate questions?

brother: Are you asking me?

me: no, i'm telling you?

brother: who are you talking to?

me: i'm talking to you?

brother: stop it???????

me: i'm making me laugh?

brother: you're making me un-install google talk?

me: no?
