If this piece makes you grab your head with both hands and mutter a guilt-soaked "oops...", I've done my day's work.
We deal here, as always, with the human mind and the laws that run it. And where the mind is concerned, let's not be naive: it is far easier to destroy than to build. Far easier to criticize than to praise. Far easier to ignore than to engage.
But if you truly want to wreck the soul of someone close and dear, I have a reliable, field-tested template for you: take your romantic partner, or your child, and punish them for the good things they do.
That will finish them off. I promise.
