Because or Why Not

Both of us sitting at either end of the couch. Under our own blankets, and deep in our own books. Our toes touching. Aware the other is there. But not thinking of it. Unless we come to a section of our book that needs sharing. Or let our minds wander to a thought we need to tell the other. Until we're back in our books.
I involved in the plot of an Agatha Cristie. Her deep in some philosophical novel. And each of us planning to read the other's. Once they're through, of course.
