Alex kept his house clean. Perhaps, he kept it cleaner than most of his friends. He did the laundry three times a week. And he did the dishes right after the meal, without exception. He even did the vacuuming right after he got home from work. He didn’t think it was too much. He liked his house clean and it helped him relax. His friends worried about it at first, but they didn’t think the same as he did. They didn’t worry about a bit of dirt and they didn’t mind a few dirty dishes in the sink. Alex and his friends were different from each other, but they didn’t think this was very important. They were good friends.
