Fact #1: We don’t let Buster on the furniture.
Fact #2: The sun shines on the couch in the morning.
Fact #3; Today is the first time I’ve seen this.
The arrow on the left is pointing to his head, stretched out in the sun on the couch. The arrow on the right is pointing to the rest of him, standing between the coffee table and the couch.
I couldn’t take a closer picture because, when I stood up to try, he picked his head up. He waited until I sat down and started using the computer before he put it back.
