Just Back Away

I got up to pee this morning. No one else was up so I didn't close the door all the way. I'd just begun to urinate when Apollo thrust open the door, leaving it totally open. He clearly wanted to be pet, but he looked really taken aback by what was happening. He looked at me peeing, and looked at the toilet, and stopped in his tracks.

Then, without turning around, he backed up, out the door. Then he wheeled around and sat on the other side of the doorjamb, looking away from me.

What a weird cat! He's got a sense of shame of seeing someone pee?
