Soporific

Topher: (while driving home from the library yesterday) Mom, sometimes I go deaf. And sometimes, I go blind.

Me: (glancing at Phoebe in the passenger seat only to discover she's just as confused by his statement as I am) Oh? Does this happen at specific times?

Topher: Yes.

Me: When?

Topher: I never hear the end of Moon Song or Mockingbird.

For context, those are his favorite bedtime songs. Based on what he said, I guess they're pretty effective.
