Two children were taken to the apple orchard on a fine day with their family. They picked a lot of apples, and had them all in a basket once they went home. Once at home, the parents told the children to each choose and apple to eat. The first child chose a glossy apple with a brilliant skin, which had no marks or dents. The second child chose a duller looking apple, with a couple of dents and some bruises. The first child bit into their Apple, only to find a worm had been their first. The worm left a tunnel in the Apple, and the child discarded the Apple. The second child bit into their Apple to find that it was very sweet, and had no worm inside. The children were careful about picking their apples from then on.
