[originaltext] Twin sisters are supposed to be very much alike, are they not

Twin sisters are supposed to be very much alike, are they not? Well, my twin sister Jane and I do look alike, however, we are different in many ways. We like very different styles of clothing. [16]I prefer to dress informally, whereas my twin sister dresses like a model, always wearing the latest fashions. We have very similar character in most ways. [17]I do not get angry easily and enioy being with friends, and in these respects, my twin sister feels the same. But she likes loud music and modern dances, while I find that nightclubs give me a headache. She is always with friends, is a favorite with all the teachers, and never wants to have any children, whereas I prefer to be alone at times, don’t really try to impress my teachers and intend some day to have a family of my own. [18]We have tried to live in the same room several times, and even agreed on the color we like best, and the kind of furniture we want, but I like to keep things neat and orderly, while my twin sister acts as if there were a servant around to pick up all the things that get thrown on the floor. I like to go to bed early and get up early. In contrast, she doesn’t seem to have any definite habits, often goes to bed very late, and then sleeps late the next day.
