Post-retirement job idea

I think once I'm old and can fashionably pass for a bitter old woman (as opposed to prematurely pass as one now), I'm going to situate myself outside the polar bear exhibits at the zoo on the regular.  That way, when snot-nosed elementary school kids with their bratty and bored parents walk by and ask "Why are they endangered Mom...what's that mean?" I'm going to say "They are endangered because you don't shut the water off when you brush your teeth, and because your mom doesn't recycle the jars of Spaghetti-O's that she serves you for dinner..IT'S ALL YOUR FAULT!"

Too harsh?
