I am confused…

Today, David and I had been having a great day.  Laughing.

The phone rang, since I had my hands in dishwater I asked him to answer it.  He put it on speakerphone.

I asked him to hold it close, instead he accused me of not wanting him around.

How does, hold the phone equal “you don’t want me around.”?

I asked him to explain it, and he doesn’t know how to.

He went from nice to mean in the space of a couple of minutes.  and continued to be ornery mean for 20 minutes.

I wish I understood, as then I could avoid whatever set him off.  Sadly, with mental illness, we may never know.
