“In the limelight I play it off fine, but I can't handle it when I turn off my night-light.”

“I'm so fast that last night I turned off the light switch in my hotel room and was in bed before the room was dark.”

“I couldn't make any judgment on the Summa, except to say this: I read it for about twenty minutes every night before I go to bed. If my mother were to come in during this process and say, 'Turn off that light. It's late,' I with a lifted finger and broad bland beatific expression, would reply, 'On the contrary, I answer that the light, being eternal and limitless, cannot be turned off. Shut your eyes,' or some such thing.”

“Dex,” she said. “Are you all right?”“I’ll be fine, Sis,” I said, feeling somewhat light-headed, “if you’ll just turn off that horrible music.”

“He won't listen to the music, and I can't turn it off.”

“Sometimes I just can't stop thinking enough to turn off.”
