Really what TuEstUnePommeDeTerre did was help us with ours. "Do your homework" is the laziest phrase, I cannot express how much I hate it. Its a phrase of dismissal. If you have a kid that is struggling, you should HELP them with their homework, not just tell them to do it. I say this because I think it is emblematic of the intellectual laziness of the folks who use this phrase thinking of it as punctuation in their winning argument.
