You can't judge a book by its cover. Appearances are deceiving. Too bad. WHAT IF every unkind thing we did/said showed up as a wart?

The warts would be indelibly set and not removable by any means including surgery. Once you had the wart you'd live with it until you died. These warts would be on the face, neck, arms, body, legs. At death some folks would have very few and some would be unrcognizable as human beings because their warts would have warts would have warts. A WHAT IF that is gruesome and awful to be sure. But WHAT IF?

Of course there is a caveat to this WHAT IF. Because saying unkind things about cruel inhuman indecent selfish greedy heartless treasonous traitorous deceitful people would not count. For example you could say all the unkind things you wanted to say about Hitler and no warts. Or Bill Cosby or Harvey Weinstein or Ted Bundy or Putin or Kim Jung Un or Duterte or Assad or the Saudis who murdered the journalist and dismembered him or those responsible for 9/11 or all the murderers responsible for the deaths of innocent people or all the rapists and pedophiles and self-centered conceited SOB's  who get off on saying hateful lies about folks they despise  or or or.
