Tonight as I put the boy to bed, he asked me, "How is this living together thing working out for you?"
It caught me a little off guard, and I answered honestly that it's going really well, and that even though there are a couple of problems, they're not relationship problems, and they'll ease and sort themselves out fairly easily and soon, I think.
Boy often has to be coaxed into communicating, so I was very, very pleased to have him initiate something like this.
It also reminded me that the little strokes of communication are just as important as the big ones. I hadn't given much thought to the question until the boy asked it.
