My wife doesn't complain often, but once she was having a old-fashioned "heart-to-heart" with me and said, "Hon, you never listen to me. Every time I try to talk to you, you get this far-away look in your eyes after only a few seconds.  Please promise me you'll try to work on that."  

The last thing I remember was replying, "I'm sorry, what was that you were saying?"
