Teasing in school is a serious problem, but sometimes we need to worry more about the teaser than the teasee. Kids who tease excessively have a problem. Some times they have been the victim of excessive teasing and they are hitting back. Sometimes they feel inferior for other reasons. It isn't easy finding the root of their problem, but when teasing become excessive, you can bet the teaser has problems. My sisters and I always teased each other a little, we still do, but it has always been a friendly thing. I don't remember ever getting mad at them over teasing. This is not to say we didn't ever get mad, it just wasn't because of teasing. Excessive teasing is a serious problem that doesn't need to be ignored.
