Painful Regret

A man came out of his home to admire his new truck. To his puzzlement, his three-year-old son was happily hammering dents into the shiny paint of the truck. The man ran to his son, knocked him away, hammered the little boy's hands into pulp as punishment. When the father calmed down, he rushed his son to the hospital.

Although the doctor tried desperately to save the crushed bones, he finally had to amputate the fingers from both the boy's hands. When the boy woke up from the surgery & saw his bandaged stubs, he innocently said, "Daddy,I'm sorry about your truck." Then he asked, "but when are my fingers going to grow back?" The father went home & committed suicide.

Regrets, regrets, that might be the main reason why humans wanted to create Time Machines, so they could undo things that they've regretted doing. Let bygones be bygones? I don't think everybody can cope with that...
