The bet with the Man City fan is that as both of our classes have 2 tests after the xmas holiday, if I got the better aggregate score (out of 200) in both tests and Liverpool beat Man City, he would need to post a picture of him wearing a Liverpool kit on Facebook, and I need to post a picture of me wearing a Man City kit if the reverse happens. However, the game ended 2-1 to Man City and it was me who scored higher, the bet is void.
