“A mystifying sensation of loneliness shook him. Arthur had been alone before, to be sure, but to be alone while surrounded by people, the one sane man in a mad place - that was loneliness.”
“If you were left alone, you'd hate it. Loneliness gets old in a hurry”
“And people are moody, dude. You gotta get used to living with people.”
“Living with someone you love can be lonelier than living entirely alone, if the one that you love doesn't love you.”
“How terribly sad it was that people are made in such a way that they get used to something as extraordinary as living.”
