Some people just don’t appreciate having a dog around. It’s sad to think there are people like that. I knew Gloria was that way—maybe that’s why she could never be truly happy.

That's the lesson of the dogs, that it's important to both live in the moment and then go on to the next wonderful thing.

Don't we, also, have unanswerable questions about the vagaries of modern existence for which the answer is beyond human grasp, so that only our faith can guide us?

I wouldn't say that I have overcome opposition so much as I have tried to understand it.
