That part with the "casual remark" is something that I experienced myself. In middle school I was bullied by a neighbour of mine. The weird part was that on some days he was really nice to me and he acted like he was a good friend of mine and on some days he was a total dick. I learned that when I approached him in the morning and talked to him (about homework, video games, whatever) he was nice to me the whole day, when I had nothing to do with him he became mean and started bullying.
