There is a well-known proverb: "The more haste, the (little) ______ speed."

Colors are sometimes called hot, cold, or neutral(中性的). Red and yellow are said to be hot colors because they make a room warmer and the walls nearer to us than they really are. We say that blue and green are cold because they give us the opposite feeling. A neutral color is one that does not seem to affect our feelings. Brown and grey are both neutral, and they may also be mixed with hot or cold colors to reduce their effect on our feelings. We can begin to see the importance of color selection. Although red might be perfect for a restaurant, it would be wrong for an art exhibition room, where we want to look at the paintings, not the walls behind. Because of its effect on size, white could be used to make a small room seem larger, or dark blue to make a large one seem smaller. Another way that we sometimes speak of a color is to say that it is loud or quiet. Again we are talking about the feeling that the color gives us. We use sound to express how much the color catches our attention.

Shopping for clothes is not the same experience for a man as it is for a woman. A man goes shopping because he needs something. His purpose is settled and decided in advance. He knows what he wants, and his objective is to find it and buy it: the price is a secondary consideration. All men simply walk into a shop and ask the assistant for what they want. If the shop has it in stock, the salesman promptly produces it, and the business of trying it on proceeds at once. All being well, the deal can be and often is completed in less than five minutes, with hardly any chat and to everyone's satisfaction. Slight problems may begin for a man when the shop does not have what he wants, or does not have exactly what he wants. In that case the salesman always tries to sell the customer something else—he offers the nearest he can to the article required. Now how does a woman go about buying clothes? In almost every respect she does so in the opposite way. Her shopping is not often based on need. She has never fully made up her mind what she wants, and she is only "having a look round". She is always open to persuasion: indeed she sets great store by what the saleswoman tells her, even by what companions tell her. Upper-most in her mind is the thought of finding something that everyone thinks suits her. Contrary to a lot of jokes, most women have an excellent sense of value when they buy clothes. They are always on the lookout for the unexpected bargain. Faced with a roomful of dresses, a woman may easily spend an hour going from one rail to another, to and fro, before selecting the dresses she wants to try on. It is a laborious(费劲的)process, but apparently an enjoyable one. Most dress shops provide chairs for the waiting husbands.
