Taking care of baby

One afternoon, a twelve-year-old boy was taking care of his baby sister while his parents went to town to go shopping. The boy decided to go fishing but he had to take his baby sister along.

"I will never do that again." the boy told his mother later that evening. "I didn't catch a thing! I didn't even get a single bite."

"Oh, next time I'm sure that the baby will be quiet and not scare the fish away," his mother said.

The boy replied, "It wasn't that. She ate all the bait."
