I have three daughters, and two step-daughters. I have taught my daughters to be respectful and to clean up after themselves, specifically to hygienically dispose of used sanitary items by putting them in a sealed nappy sack before placing in the bin. I have a long running dispute with my step-daughters where they refuse to do this, and simply dispose of their items in the bin. I feel aggrieved that I am constantly cleaning up after them, and frankly this makes my stomach turn. It's got to the point where my husband will clean the bin to avoid an argument, but my point is that they need to learn, otherwise they will expect other people to do things for them all their life. AIBU?
