How does Christopher feel about the rooming house?

In Chapter 233, Christopher and Mother move to another house, where she rents a room. Christopher doesn’t like it much because he has to share a bathroom with people he doesn’t know, and the hallway smells like bleach and gravy. Besides, the walls in the room he shares with his mother are brown. Things get better, however, when he helps Mother repaint them White with a Hint of Wheat.
