When I was 19yrs old I did a semester in Japan living with a host family. They were a young couple in their early 30's, 2 young kids, lower middle class working family. Most other students were assigned to live with wealthier families but those kids paid attention and filled out their family match forms. I made the most of it and ended up staying up after dinner with the couple and really practicing Japanese. They spoke almost no English but had millions of questions. They wanted to touch my hair and each night asked more and more personal questions.
