No sometimes I’m on the John LOL. For me there is really no need to ponder it more than for entertainment. But I certainly will allow you to wonder about it. Maybe your dog is doing the same…That doesn't make sense. You only know that a human is "wondering if we're alone" because that human has a conversation with you about what he's thinking. Why would you think you would know such a thing from an animal in which you have limited knowledge of how to communicate with.
Seriously what's the physical expression or interpretation of the question " are we alone"? Do you always look at the night sky when you think of that question?
Just something to think about.
And I say that thinking my dog is pretty damn smart for a dog. If I say “let’s go for a walk”, she won’t leave until she is satisfied that my wife isn’t getting ready to go for a walk. If my wife is doing anything else, my dog runs out the door. If my wife is dressing for a walk, my dog sits and waits for her. She does the same for me. We call her the “thinker”. But she’s not reinventing the dog bowl, she’s just waiting for something to be in it.
