     If I could select a word that best describes the majority of American parents, that word

would be guilt-ridden (内疚的). How sad it is to see parents become the willing victims

of the "give me game", only to discover that, no matter what they do, it isn't enough. In the

end, they are looked down for their lack of firmness and blamed when their spoiled children

get into trouble. With this in mind, I shall first answer this question: "What do parents owe

their children? And I shall start with what they don't owe them.

     Parents don't owe their children every minute of their day and every ounce of their energy.

They don't owe round-the-clock car service, singing lessons, tennis lessons, an expensive car

when they reach sixteen, or a trip to Europe when they graduate.

     I take the firm position that parents do not owe their children a college education. If they

can afford it, fine. But they must not feel guilty if they can't. If the children really want to go,

they' II find a way. Here are plenty of loans and scholarships for the bright and eager who

can't afford to pay.

     After children marry, their parents do not owe them a house or money for the furniture.

They do not have an obligation to baby-sit their grandchildren when the parents were on

vacation. If they want to do it, it must be considered a favour, not an obligation.

     In my opinion, parents do not owe their children an inheritance, no matter how much

money they have. One of the surest ways to produce a loafer is to let children know that

their future is assured.

     Do parents owe their children anything? Yes, they owe them a great deal.

     One of their chief obligations is to give their children a sense of personal worth, for

self-esteem is the basis of a good mental health. Parents owe their children firm guidance

and consistent discipline. Parents owe their children privacy and respect for their personal

belongings.

     No child asks to be born. If you bring a life into the world, you owe the children something.

And if you give him his due, he'll have something of value to pass along to your grandchildren.
