Randomness!!

Having an exchange student live with you can be quite an experience. We have one right now from South Korea living with us. So far it has gone really good. We have been blessed with a boy that is very easy going and pulls his own weight around the house. Sure it is an adjustment to having them live with you and your family, but we all have adjusted just fine. I think it is a good experience for most families. It allows the kids to be able to learn to work with someone else living in their house and probably have to be less selfish when it comes to things. I think of the shower situation. You usually are in some sort of schedule with your family, but adding another member changes this. So you have to be more patient or laid-back about it.
In-closing having an exchange student can be a good experience depending on the student and your family.
