My breathing

Wife telling me the current temperature.

The cat purring

Just my own breathing again.

Repeat of PBS News Hour in the background. :shrug:

Nothing-these noise-cancelling headphones work pretty nicely, and I haven't started the music yet.

The narration of a chess game from one of the online channels I follow.

The weather channel ...

:shrug: Darn still not spring.

My own chewing.

Me humming

Political commentary from my 'puter.
