My wife and I hosted a second exchange student from Germany last month. We had a great time with her and as always we learned a little more about the world and about ourselves. We still keep in touch with the student we hosted a year ago and we hope the same will happen with this recent one. It is fantastic to have friends all over the world.
If you have ever thought about hosting a student, try it, you might like it. I definitely had reservations with the first one but after having him, it was fun, so we decided to host another one this summer. So far we have only hosted students for a month during the summer. Maybe we'll host one for a year if we get up the nerve.
