This weekend we had a couchsurfer over. Couchsurfing is a way of traveling where you stay with people you don't know, who offered their couch to other people they have no idea exist. Everyone hopes nobody gets stolen from, and in the end everyone is happier because of the experience.
The guy who came over wanted to see the Ronde van Vlaanderen (Tour of Flanders), a famous bike race. We hung out and talked about our experiences in life, and got along great. Definitely something to try again.
