" The school is teeming with activity. The rooms are small and large, many are special-purpose rooms, like shops and labs, but most are furnished like rather shabby living or dining rooms in homes: lots of sofas, easy chairs, and tables. Lots of people sitting around talking, reading, and playing games. On an average rainy day—quite different from a beautiful suddenly snowy day, or a warm spring or fall day—most people are inside. But there will also be more than a few who are outside in the rain, and later will come in dripping and trying the patience of the few people inside who think the school should perhaps be a “dry zone.” There may be people in the photo lab developing or printing pictures they have taken. There may be a karate class, or just some people playing on mats in the dance room. Someone may be building a bookshelf or fashioning chain mail armor and discussing medieval history. There are almost certainly a few people, either together or separate, making music of one kind or another, and others listening to music of one kind or another. You will find adults in groups that include kids, or maybe just talking with one student. It would be most unusual if there were not people playing a computer game somewhere, or chess; a few people doing some of the school’s administrative work in the office—while others hang around just enjoying the atmosphere of an office where interesting people are always making things happen; there will be people engaged in role-playing games; other people may be rehearsing a play—it might be original, it might be a classic. They may intend production or just momentary amusement. People will be trading stickers and trading lunches. There will probably be people selling things. If you are lucky, someone will be selling cookies they baked at home and brought in to earn money. Sometimes groups of kids have cooked something to sell to raise money for an activity—perhaps they need to buy a new kiln, or want to go on a trip. An intense conversation will probably be in progress in the smoking area, and others in other places. A group in the kitchen may be cooking—maybe pizza or apple pie. Always, either in the art room or in any one of many other places, people will be drawing. In the art room they might also be sewing, or painting, and some are quite likely to be working with clay, either on the wheel or by hand. Always there are groups talking, and always there are people quietly reading here and there. One "
