What on earth makes me think I want to go and live in America for a year? I think I must be utterly barmy. I won't know anyone, I can't figure out how the New York subway system works, I can't even understand the maps, the vegetarian food is rubbish, I won't be able to understand anyone talk, I know my students, I know how to teach them, what to teach them and how to make them behave for me (most of the time, anyway).
I have friends here, good friends. I have a life, a happy contented life.
I want this, I do want this but today it's all become terrifyingly exciting and terrifying at the same time.
