Sleeping buddies

My parents came to visit us last weekend. After we greeted each other at the door, my dad walked over and sat down on our sleeper sofa. Sadie, who was not feeling well at the time, walked over to him and lowered her head so my dad could give her head, neck, and ears a good rubbing. (She'd stay there for hours if we could keep it up.)

Then, as she had done during my parents' last visit, she climbed onto the sofa and laid down next to Dad, resting her head on his side. Eventually, the two of them fell asleep. I had to capture the moment:

I had a decision to make before I took the picture: who do I focus on? I decided that I wanted Sadie to be the subject, so I put her in focus and had my dad be just out of focus. I guessed that using an aperture of f/4 would give me what I wanted. Using center-weighted metering I set my exposure compensation to -0.7 because there was a lot of glare behind them. I must have been an amusing sight to see as I stood, knelt, and changed my viewing perspectives attempting to convey what I was trying to say.

Eventually, Indy the cat came over and sat in front of them for awhile. He stared that cat-stare that they all have, and then left. I have no idea what Indy was thinking.
