Upside down

Sometimes I'm lying down and my human gives me chin tickles, and I enjoy it so much that I tilt my head right back... then I lay on my back.

When I open my eyes, everything looks funny. The world is upside down.

The chairs are upside down.
The doors are upside down.
The things on the walls are upside down.
My human is upside down.

I like lying on my back.
