Well, too be honest the ones that I've met have almost always been under 20 at the time. (No longer would they be that young, but this was years back) and they where all very nice and appreciative of any attention you paid to them.
They especially liked me because at the time I knew a fair deal more Japanese then I do today, enough in fact that in a very primitive fashion I could usually convey my meaning at least enough for them to understand in their language. Then they would typically respond in English and so we where able to work on our second languages.
Alas... I haven't had anyone to practice with in ages, and so I've lost most of it. I can still write out 90% of one of their primary alphabet, and I can still say a couple of things.
Mainichi hanbaga desu ne!
Mael probably laughed. (it was from a skit that I happen to remember. We did lots of them)
"George Bush says he speaks to god every day, and christians love him for it. If George Bush said he spoke to god through his hair dryer, they would think he was mad. I fail to see how the addition of a hair dryer makes it any more absurd."
