Having Kids Makes You Happy

When I was growing up, our former neighbors, whom we’ll call the Sloans, were the only couple on the block without kids. It wasn’t that they couldn’t have children; according to Mr.Sloan, they just chose not to. All the other parents, including mine, thought it was odd-even tragic. So any bad luck that happened to the Sloans--the egging of their house one Halloween; the landslide(山崩) that sent their pool careering to the street below-was somehow attributed to that fateful decision they’d made so many years before. "Well," the other adults would say, "you know they never did have kids." Each time I visited the Sloans, I’d search for signs of insanity, misery or even regret in their super clean home, yet I never seemed to find any. From what I could tell, the Sloans were happy, maybe even happier than my parents, despite the fact that they were childless.
