Back when we were swapping prints on the porch and burning CDs for road trips and you'd just tuck a picture back in the envelope and say, I won't keep you. That still works. I'll say let me let you get back to your day, always nice to see you, and I start ambling the other direction. If I've got a reason handy I mention it, headed to the post office or the kettle's on. The tone is neighborly and brief, and the wave does half the work.
