Why is it hard to handle criticism?

Yesterday I wrote about the need to handle criticism with grace. I got a few emails and one of my friends suggested something that resonated well with me.

When a person is criticized, typically its a “disapproval of something”
that the person has done. However, the person criticized can’t
dis-associate himself from something he has done. He thinks its a
“disapproval of him” and naturally he launches into defend or attack.

Something to think about!
