Ask a bachelor why he resists marriage even though he finds dating to be less and less satisfying. If he’s honest， he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun， adventure， excitement. Marriage has such movement， but they are not its most distinguishing features.
Similarly， couples who choose not to have children are deciding in favor of painless fun over painful happiness. They can dine out whenever they want， travel wherever they want and sleep as late as they want. Couples with infant children are lucky to get a whole night’s sleep or a three-day vacation. I don’t know any parents would choose the word fun to describe raising children.
