I am assuming that the "demeaning" text is the one that says, "Really?!?!?!".
Based on that assumption, I think it's worth a laugh. I don't think anyone "owes" anyone anything, except perhaps your kids owe you a thorough kitchen cleanup.
There are far worse things over which to lose your marbles. Teach the kids. Monitor their progress. Model forgiveness and humility.
I'll stop there, lest I type another sermon.
