There was a little boy visiting his grandparents on their farm. He was given a slingshot to play with, out in the woods. He practiced in the woods, but he could never hit the target. Getting a little discouraged, he headed back to dinner.
As he was walking back, he saw Grandma’s pet duck. Just out of impulse, he let fly, hit the duck square in the head, and killed it. He was shocked and grieved.
