COUCHSURFING EXPERIENCE I hosted some exchange students in my house. I am nested into this

I once hosted a group of Dutch student at my university for a tour. They contacted me via a friend of mine who is i Frnace for erasmus exchange. They came to our school and when one of the guys asked me where I have been in the Netherlands, we suddenly realized that we had a common friend who was his classmate and my exchange friend. What a small world.
