It was still light outside, just a little, when the children’s mother lay down in the spare bed with the younger child to help him sleep, their usual kind of tucking-in ritual, just without the sheets. Except that she too was enervated by the heat and when I looked in, half an hour later, she was curled up on her side and snoring gently. The dog, never one to let the barest hint of an opportunity pass her by, snaked around my legs and up onto the mattress in one swift movement, turned her habitual three circles and settled in too. I let them be and returned to my book on the couch downstairs.
