While I just started reading it bc I was in a grumpy and annoyed mood I thought I would read about a grumpy teenager and actually ended up liking it much more than expected. The first half was a bit slow but later it got actually funny, a teenager kicked out of school again trying to "survive" a few days in a big city before going back home, doing stupid things. As far as I know this is required reading in a lot of American high schools but is probably more enjoyable as an adult if you don't take him too seriously
