Billy covered his head with his blanket. He always covered his head when his mother came to see him in the mental ward - always got much sicker until she went away. It wasn't that she was ugly, or had bad breath or a bad personality. She was a perfectly nice, standard-issue, brown-haired, white woman with a high school education. She upset Billy simply by being his mother. She made him feel embarrassed and ungrateful and weak because she had gone through so much trouble to give him life, and to keep that life going, and Billy didn't really like life at all.
