Russians are friendly, but they usually keep to themselves. They aren't used to American's friendiness.
Would I want to visit Russia again? I don't think so.
If I remember correctly -- Russians don't like for windows to be raised/opened even if it is so hot.
Jiro, you should go to Dubai to surprise your buddy. There is no doubt, you'll like Dubai. I loved it. I would move there if it is that friendly for deaf people like myself.
