Alex keeps his house clean. Perhaps, he keeps it cleaner than most of his friends. He does the laundry three times a week. And he does the dishes right after the meal, without exception. He even does the vacuuming right after he gets home from work.
He doesn't think it is too much. He likes his house clean and it helps him relax. His friends worried about it at first, but they don't think the same as he does.
They don't worry about a bit of dirt and they don't mind a few dirty dishes in the sink. Alex and his friends are different from each other, but they don't think this is very important; they are good friends.
