How often one hears children wishing they were grown-ups and old people wishing they were young again. Each age has its pleasures and its pains, and the happiest person is the one who enjoys what each age gives him without wasting his time in useless regrets.

Childhood is a time when there are few responsibilities to make life difficult. If a child has good parents, he is fed, looked after and loved, whatever he may do. It is impossible that he will ever again in his life be given so much without having to do anything in return. In addition, life is always presenting new things to the child — things that have lost their interest for older people because they are too well-known. But a child has his parents. He is not so free to do what he wishes to do; he is continually being told not to do things or being punished for what he has done wrong.

When the young man starts to earn his own living, he can no longer expect others to pay for his food, his clothes, and his room, but has to work if he wants to live comfortably. If he spends most of his time playing about in the way that he used to as a child, he will go hungry. And if he breaks the laws of society as he used to break the laws of his parents, he may go to prison. If, however, he works hard, keeps out of trouble and has good health, he can have the great happiness of building up for himself his own position in society.

The easy way out isn't always easiest. I learned that lesson when I decided to treat Doug, my husband of one month, to a special meal. I glanced through my cookbook and chose a menu(菜谱) which included homemade bread. Knowing the bread would take time , I started on it as soon as Doug left for work. As I was not experienced in cooking, I thought if a dozen was good, two dozens would be better, so I doubled（加倍）everything. As Doug loved oranges, I also opened a can of orange and poured it all into the bowl. Soon there was a sticky dough (面团) covered with ugly yellowish marks. Realizing I had been defeated, I put the dough in the rubbish bin outside so I wouldn't have to face Doug laughing at my work. I went on preparing the rest of the meal, and, when Doug got home , we sat down to eat Cornish chicken with rice. He tried to enjoy the meal but seemed disturbed. Twice he got up and went outside , saying he thought he heard a noise. The third time he left, I went to the windows to see what he was doing. Looking out, I saw Doug standing about three feet from the rubbish bin, holding the lid up with a stick and looking into the container. When I came out of the house, he dropped the stick and explained that there was something alive in our rubbish bin. Picking up the stick again, he held the lid up enough for me to see. I felt cold. But I stepped closer and looked harder. Without doubt it was my work. The hot sun had caused the dough to double in size and the fermenting yeast (酵母)made the surface shake and sigh as though it were breathing. It looked like some unknown being from outer space. I could see why Doug was so shaken. I had to admit what the “living thing” was and why it was there. I don't know who was more embarrassed(尴尬)by the whole thing -- Doug or me.
