Good advice from everyone, and I take it all under advisement.
It offends my daughter’s young sensibilities that her brother might actually “cheat” by using her roll. He is equally offended that she will not dispose of her personal products (pads) in the toilet, which we promptly educated him about - NO, NO, NO!
As far as scrutinizing their bathroom habits, k2dave, we aren’t terribly interested in what they’re doing in there, but more that we’re trying to teach them not to waste too much - raising two teenagers is incredibly expensive and preparing them for the day they leave our home and become responsible adults is our goal.
We do all of this with a good sense of humor; of course, they think it terribly unfair we limit shower time to 10 minutes (and we’re not against tossing a glass of cold water at them if they ignore the knock on the door when time’s up!)
And Binarydrone, I know what you mean about the Whirrrrrr of the roll - sometimes when the husband is “indisposed” he has awakened me from sleep many the morning. But at least I know he wipes:)
