I did a German exchange when I was 15
I was matched with a boy called Christian - I think they matched us as I said on my form that I played badminton (which I did, for fun sometimes) and he played tennis (to a very high level).
I think it’s fair to say that we had very little in common
German schools start early and finish about lunchtime - so the kids can go off and do sports and things. Every day I had to accompany him to an indoor tennis place - where he would play tennis. I was never allowed to join in. I was just expected to sit there and watch
When he stayed at mine I got my revenge by making him sit through videos of The Greatest Rock’n’Roll Swindle and Spinal Tap. God knows what he made of them
