A few years ago, in response to some darn thing a younger co-worker said, I gave her an honest broad estimate of how many time my wife and I had made love. She started calculating, and after a bit announced that that came to 3.4 times per week; which was actually about right, along about then. What I later regretted was, I didn't think to say, "And I'm getting darn sick of all those times that we get four-tenths of the way, and my wife makes me stop!"
