Does anyone know french?

In t-minus 5 days I will become a host mom to a 16 year old French boy.  My neighbor coerced convinced us that we should help with the HOST Chicago program that is bringing in 2 groups of French foreign exchange students for 3 weeks. It is a little odd, a young couple with no kids hosting a teenager.  Especially since both of us work full time during the week, but with help from the neighbors and them having teenagers themselves it should be no problem.  In truth, I'm actually fairly excited. Should be quite the experience.
