Just a side note:
Whilst working at my school I’ve noticed a few quirks with their English. They tend to learn British English, but pick up a lot of American pronunciation and slang. Normally you can decipher through things, but sometimes it gets a bit awkward. One that’s hard to get used to though is the British word for an eraser, which they call a rubber. In America, this is a common term for a condom.
Needless to say I’m very startled everytime students ask the teachers, their peers, or me for a rubber.
