It's inevitable that when one Marching Mommie discovers someone doing something of which she disapproves -- and poking his eye out or bumping his head or gaining five lb. --, her instant response is to begin screaming that ALL of humanity be prohibited from doing that one thing, even though she can point to no similar result of that behaviour anywhere. That way nobody ever learns from anybody else's mistake. "Doctor," goes the old joke, "it hurts when I do this." "Then," says the doctor in the joke, "stop doing that!" This is funny because it's senseless -- yet Mommy nods wisely.
