Househusbands

Dear Editor,

I read with interest the article on American families. In general I agree with it, but there are some important things it left out. It didn't tell the reader much about the life of a househusband. It's not an easy life. I know, because I'm now a househusband myself. A househusband has to change many of his ideas and his ways.

First of all, he has to change the way he thinks about time. Before I was a househusband, I worked full-time for the New York Times. I was a reporter, and time was always important. We had to finish our article quickly and give them to the editor. Everyone was always in a hurry. This is the way, many other men work, too. Businessmen, lawyers, bankers, and doctors all have to work quickly.

At home it's different. The househusband cannot be in a hurry all the time. If you rush around, you will make everyone unhappy! The children will be unhappy because they don't understand. For them, time is not important. Your wife will be unhappy because the children are unhappy. You will be unhappy, too, because they are all unhappy. So you have to learn to slow down. That is the first and most important rule for a househusband.

There is something else the househusband must learn. You must learn to show how you feel about things. At work, men usually do not talk about feelings. If they do, people think they are strange. So, many men are not used to telling anyone about their feelings. They do not know how to talk about their anger, worries, or love. But children need to know how you feel. They need to know how much you love them. If you are angry, they need to know why. Your wife also needs to know about your feelings. If you do not say anything, your family may get the wrong idea. Then there may be serious problems.

People talk a lot about househusbands these days. Usually they talk about men doing the housework, the cooking, cleaning, and shopping. But in my opinion, these are the easiest things to learn. It was much harder for me to change the way I think and the way I act with my family. I think, other men will also find this harder, but, like me, will find it necessary if they want to have a happy family!

The modern comic strip started out as ammunition in a newspaper war between giants of the American press in the late nineteenth century. The first full-color comic strip appeared January 1894 in the New York World, owned by Joseph Pulitzer. The first regular weekly full-color comic supplement, similar to today's Sunday funnies, appeared two years later, in William Randolph Hearst's rival New York paper, the Morning Journal.

Both were immensely popular, and publishers realized that supplementing the news with comic relief boosted the sale of papers. The Morning Journal started another feature in 1896, the "Yellow Kid," the first continuous comic character in the United States, whose creator, Richard Outcault, had been lured away from the World by the ambitious Hearst. The "Yellow Kid" was in many ways a pioneer. Its comic dialogue was the strictly urban farce that came to characterize later strips, and it introduced the speech ballon inside the strip, usually placed above the characters' heads.

The first strip to incorporate all the elements of later comics was Rudolph Dirks's "Katzenjammer Kids," based on Wilhelm Busch's Max and Moritz, a European satire of the nineteenth century. The "Kids" strip, first published in 1897, served as the prototype for future American strips. It contained not only speech balloons, but a continuous cast of characters, and was divided into small regular panels that did away with the larger panoramic scenes of earlier comics.

Newspaper syndication played a major role in spreading the popularity of comic strips throughout the country. Though weekly colored comics came first, daily black-and-white strips were not far behind.. The first appeared in the Chicago American in 1904. It was followed by many imitators, and by 1915 black-and-white comic strip had become a staple of daily newspapers around the country.

The word “prototype” in the third paragraph is closest in meaning to ________. 

A. story

B. humor

C. drawing

D. model
