I disagree, because I was bullied/teased for 3 years in Elementary School! 4th, 5th, and 6th grade were hell for me and my mother knew about it and did nothing about it, neither did at least my 5th grade teacher! It went on outside the classrom at recess and lunch time, when the teachers weren't around. The boys started it with name calling and the girls wanted to be popular with the boys, so noone would openly be my friend, even the ones who were my "friends". In 6th grade I was pushed into a fight with a tough girl and they formed a ring around me so I couldn't escape, expecting me to be pummeled. My only defense was to dig my nails into this girls arms. I dug so hard I drew blood. It wasn't character building, it made me ashamed and I ran and hid for the rest of the day. It lowered my self-esteem, not made me who I am!
P.S. since I didn't Multi-quote, the popular boys/girls were NOT popular because they were outgoing and friendly. Quite the opposite, they were mean!!!!!
At least one of instigators grew up and actually initiated saying "hi" to me at my 20th high-school re-union!
