This little scenario was performed by yours truly to an unappreciative audience, several times. Yet, the concept of replacing the roll seemed to elude an otherwise capable crew. I took to putting the roll on the seat in full view with the hope that it would be correctly reinserted in the aperture created for it. Eventually, I gave up. You have to pick your battles, I guess, and in the scope of large family concerns, this was not on the radar. It pleases me no end now to see my kids in their own homes replacing their rolls with skill and dexterity. I guess you can teach by example after all.
