Mother Knows Best? Once while being prepped (准备) for a television interview, I was chatting with the host about stay-at-home fathers. I made the point that one reason we're seeing more stay-at-home dads may be that it's no longer a given (假定的事实) that a man makes more money than his wife. Many families now take earning power into account when deciding which parent will stay home. At that point, one of the male crew members commented, almost to himself but loud enough for my benefit, 'It should be the better parent who stays home. ' A lot of guys say things like that. Usually it's a code for, 'My wife, (read: any woman) is the better parent.' I was a stay-at-home father for eight years, so his declaration made me bristle (激动). It implied that our family's choice could only have been correct if I was a ' better' parent than my wife. I suppose an argument could have been made that when I began staying home my wife was the 'better' parent: She I-Dad spent more time with Ry, could read him better and calm him more quickly. And given a choice, he'd have picked her over me. But as she was the more employable one, my wife went out to work and I looked after our son. Because of the increased time I spent with him, I soon knew Ry well, understood what he needed and could look after him more or less as well as my wife could. Actually, the experience helped me unlock one of the world's great secrets: Women are good at looking after children because they do it. It's not because of any innate (先天的) female aptitude (天资) or a mother's instinct. It's because they put in.the time and attention required to become good at the job. Women obviously get a biological head start from giving birth and nursing, but over the long term experience is more important. When I got the experience myself, I was good, too. As good? I don't know. Who cares? Children are not made of glass. Other people are capable of looking after them besides Morn. Which of the following does the first paragraph imply?
