As a child, you learn the concept of a hot stove. Mom says "hot," and that means bad, and that you shouldn't touch it. You learn it again (or at least we did, when we were small) when you see the Bugs Bunny public service announcement, which is not so much about not touching the hot burners on the hot stove (which will in fact burn your fat little hand, and possibly cause a paralysis/nub situation), but more about keeping the pot handles turned in. "Keep those pot handles turned in!," says Bugs.
He was smart, Bugs. Anyone with common sense knows to not keep going back to something that harms you, and without any rewards.
