I'm back in Japan. I had trouble at the airport in the morning when I would come back to Japan. My flight was delay for 2 hours. After all I had to change the airplane and my arrival in Japan was late. But, anyway, I could safely come back to Japan. While I stayed in USA, thank you for your kind comments!
Whether or not your learned a lot, did you put your english to use more? Are you now faster when thinking in english?
See you, greetings from Chile.
