What would you never tell a woman that you can do better

I would never tell a woman I can do anything better than her because I know there are things that I can't, and even though I can on somethings it would be antagonistic to tell her so. My wife and I operate this way. She knows there are thing that I do better and she prefers to let me handle it, and I know that there are things she does better than me so I prefer to let her take care of those.

"write" my name in the snow ?
