I know the feeling. This is the way things work out for me at work. I work and keep silent and get the most of workload over and over again and if I don't do something like one time I get an earfull. Though sometimes it gets too much and a few weeks ago I wrote a huge letter to the headmaster speaking my mind on the subject of his treating and we don't speak and pretend not to notice each other ever since. I hope Harry will fight back though:))
