Some things are important to teach and discuss, but we're afraid to talk about them. Well one teacher took it upon herself to teach her young students how to wash their butts after using the potty. Millions of people are applauding her and saying it should be taught in every school. (I personally think parents should have taught them the basics of wiping before this.)
Credit this teacher with an ingenious lesson plan. Using balloons to illustrate butt cheeks is brilliant.
