I'm not necessarily disagreeing with you about the parent's tone (though I think "attack the character" is not really accurate). However: > Please do better.

I'm not necessarily disagreeing with you about the parent's tone (though I think "attack the character" is not really accurate). However: > Please do better. This specific phrase, especially as a standalone sentence, comes off as highly superior/patronizing. It's almost exclusively something you would say to a child, or as a humble resolution about yourself.
