Difference Between Speaking English and American

I was born in England to two American parents. When it came time to move back to the Americas I naturally had to go to American schools. Can you imagine walking up to your sixth grade principal and asking him if you can continue taking Latin and French. Boy was he surprised. Anyway, I was sitting in class one day and made a mistake on my paper so I naturally turned around and asked the girl behind me if I could borrow her rubber. Boy, if I knew what I was doing I would have been very embarrassed.
NOTE: A rubber in England is an eraser.

She was surprised that I wasn't embarrassed or angry when she called me a fag. After all I was quite confused with her statement!
NOTE: A fag in England is a cigarette.
