Kill Bill's a non-stop joyride but Pulp Fiction's a bore. I honestly don't know why Pulp Fiction got some awards.

One of my favorites!

That's really nice of you, Lynn! I'm sure a lot of teachers in Shanghai will take you up on your offer. If I were only there, I'd contact you right away.

Don't worry about it Sophie. I'm sure boys all over the world are going to fight for the right to date you!

It's a non-standard contraction for "am not, is not, and are not". "Ain't" is used only in informal situations and never in writing. If I were you, I'd avoid using it. Just stick to the standard contractions "I'm not, isn't, and aren't".

I couldn't agree with Mr P more that the sentence should read "I couldn't agree with you more!"

I'd use 4 too.

"I can't agree with you any more." I haven't encountered this sentence before. The way it's worded, it seems to mean "I've been agreeing with you but (I'm fed up so) I can't/won't (agree with you) any more."
