how taller people are stronger and better at tug-of-war. My son was the shortest one in the class and was subsequently made fun of. As he began telling me, I knew where it was going because to me it was obvious--if you classify 7th graders based on physical appearance and characteristics, you are guaranteeing that some of them will be made fun of (at least if it's height and/or weight; eye color or hair color I think would be less likely to lead to teasing). That's just my thinking. As a teacher, to me it would be obvious. Am I off base here? Am I wrong to think this probably isn't a good exercise, or is it harmless fun and people just overreact?
