Trying to "help".
/Growing up, I was always a bit heavier than my peers. I never really noticed, though, and never let it get in the way of having fun.
The first time someone pointed it out was humiliating. It was in second grade gym class.
The coach allowed certain people to slack off in class, while remaining very strict with a select few. I was in the second group. The coach always told me to work harder and do better, and I never understood why.
When I finally asked, the coach admitted that he was trying to "help" me by making me do more so that I could lose weight.
Needless to say, it hurt.
