Dear Aunt Mei:
I can't believe I've been in London for 6 months already! I certainly owe you an apology for not writing more often. I've just been so busy studying and trying to absorb all the new things around me. I think I'm still experiencing culture shock. There is so much here that is different from home. But you'll soon experience it all yourself! I wish your visit wasn't going to be so brief but there's a lot we can do and see in a week. I'm just so glad you can afford to visit me and I refuse to let you pay for anything while you're here! I don't know what your expectations are of London, but knowing that you've never traveled outside of Asia, I thought I'd tell you a bit about what you can expect to find.
