Every night before bed, our five-year-old goes into the bathroom to take care of business. We often have to call in and ask if he's done. One night last week he was in there for a particularly long time. My husband asked him why he didn't let us know when he was done. Our son said, "I got distracted, I was thinking." Curious, my husband asked what he was thinking about. The answer: "I was thinking about toys on the other side of the earth."
