Things you do when no one else is looking

Sing to my dogs
Read aloud (often to my dogs)

I sing like all the time when no one's around, usually made-up songs, often about the things that I'm also doing while no one's around. But more often I'm just repeatedly singing some stupid rhyme or phrase that I'm inordinately pleased to have discovered. I occasionally wonder if my brain is well.

I wrote a song about Yogurt Burt earlier. While eating yogurt. I don't know who that is.
