How exciting! Can you get the pajamas delivered? Because that would be awesome. It's a good thing McD doesn't deliver here. I'd have a hard time resisting those breakfast burritos if they could show up toasty on my doorstep.
My sister spent 6 months in South Korea teaching English. I really wanted to do something like that in China, but then I got married and babies...
I hope you have tons of fun and make lots of friends! Do you know the language already? That's probably my biggest fear- not being able to talk to people or even read anything.
