Last Saturday was our sixth anniversary, and though you wouldn't know it because we never post on the weekend anyway, Darwin and I went off to a B&B for the weekend. (Grandma is in town for an extended visit, so we knew the girls were in good hands.) Over breakfast, we met a pleasant elderly couple with whom we exchanged basic background information and general conversational anecdotes. The wife told me how her mother had had four children in five years: "Then (this is how she put it when she told me -- it was the 50s, after all!),'We figured out what caused that, and got it fixed.'"
My immediate thought was, "They never had sex again? That's too bad!"
