True Bumper Sticker

You know what? Mean people Do Suck.
I had someone say something to me that was thoughtfully designed to sting. It's a different sensation than when someone is accidentally hurtful. It's perplexing, you know, to have that dawning realization that another human being gave some specific thought to how best to inflict some pain.
In the heat of an argument, it's common to say things that are unkind, even deliberate. But to calmly and thoughtfully deliver such leaves me mystified. All I can think, is, "Huh?"
What a shame.
It reminds me how dirty one gets when one tries to sling mud.
