When I was a kid...

...another kid called me "fat" during gym class, and I unleashed a torrent of abuse in response. I possibly punched him. I actually don't remember.

No one in gym class called me fat again. In fact, no one at all has called me fat since (except for me).

I knew he was right. But I knew that he didn't have any right to observe my fatness to me outloud, in public, joking or not.

So I yelled at him. I'm glad I did.
