One of my friends immediately jumped up to buy some.

She bought 7 books for 7.50.

I don't even know how many times I told her it was $7.50. I bought her books and told her to just pay me backs.

I'm a little pissed because she paid me back but she only gave me four bucks.

My Little hissy fit is pretty stupid but I feel kind of...mistreated? Is that the right word? I mean, I have trouble pointing these things out to people, I'm afraid they'll hate me, but I don't want to be used.
