Not having my mistakes pointed out to me is hurtful to me, and what’s hurtful to me . . .
You’re totally misapplying the concept. You can’t do something to someone else which is hurtful to her, just because it’s not hurtful to you.
Also, your mistake is being pointed out to you, yet you don’t seem to taking advantage of the opportunity to improve yourself.
Really, I don’t think you’re trying to be rude and hurtful, but can’t you accept it, when a number of posters have pointed it out to you?
