Ditto on the cultural change, and sometimes the language :D I had a little yard sale here years ago, and a little boy came and wanted to buy something. I couldn't understand a word he was saying, the little twang he had was so pronounced. My friend sat there as clueless as I was until her husband came over to help. He's from Mississippi and when he listened to the boy's request he acted as though we were the ones with the problem, which of course we were. It was like listening to a foreign language.
I have every confidence that you do exceptionally well in the transition.
