I don't know anyone like I know myself.

I don't allow myself to be overweight. It's just not right for me.
If I let myself go, however, I think I'd be awakened by someone shaming me a little.

It is unacceptable to me for me to be fat so I probably shouldn't pretend that my response to shaming would be normal. It's possible that fat people who don't mind being fat would not be positively affected by shaming.
