I think this comment was said to my son in 3rd or 4th grade. His teachers asked him if his mother helped him with his work or if he worked on it all by himself :S
Quite frankly, he never really liked any help and after this comment, he was determined never to ask me. He wanted to figure out his work on his own and thought his mother helping him was "insulting". I wonder if these teachers had not said these things....my son would be more accepting of my assistance.
I learned early on... my son had to do things "his way" and couldn't be pushed to something he didn't particularly enjoy easily... so I had to be careful to pick my battles.
