I always hated my teachers, except for my fifth grade teacher. He was awesome. He is still around.
Some of my teachers had a pretty rough ending. One was committed after going insane over the loss of her son (he killed himself in front of her after a discussion) and killed herself during her time in the mental institution. Another teacher of mine died in an airplane, ironically after avoiding the previous plane over thinking that said plane would crash and kill him, and the third teacher was shot and didn't have medical care quick enough to save her life. But those were just three of them.
