The US Navy sent me to Japan in 1970 (had no knowledge of Japanese at all). I still laugh at myself for saying Hi to all the Japanese I heard saying "hai" and thinking how friendly they all were to take the time to say "hai" to me. My other big shock was the "mamasans" on base that did the cleaning. My first day on base I was in the shower when the mamasan came in to clean and I almost broke my neck trying to get to my towel to cover up. It's been over 40 years since I was last in Japan , and I still have many wonderful memories of the country and it's people.
