Just a quick answer, more later. I go to Japan once or twice a year, for 1-3 weeks at a time.
Are the dynamics different there? Well, I must say I am something of an a$$ while I am there sometimes, partially due to jet lag and partially due to being away from my routine.
My kids are so much smarter than I am it's pathetic. They are so close together, it's a joy to watch. I know that will wane, but it hasn't yet.
I've tried to be comfortable with the fact that she plans her life, and therefore mine, with the help of a Japanese fortune teller. The FT said that next year isn't going to be so good. Boo-Hoo!
