PDA for parents

A few days before we left town for Christmas, I got together with a friend for coffee. While I sat waiting for her, and sipping a gingersnap latte, a young couple came in and sat at the table next to me. They were, to put it bluntly, all over each other. They sat elbow-to-elbow, hands clasped, whispering sweet nothings over their lattes, and every now and then they kissed in a long and lingering way.
