What did you say?

After I discovered that I had ADD, I began the process of analyzing myself.  So many aspects of my life, my personality, my habits, etc. appeared not to be normal!  During one occasion, my wife and I were sitting at the dinner table and she began telling me something.  After about 10 seconds of her talking I laughed and asked her to stop.  I had not heard a word of what she had said.  Then, I literally listed the five totally unrelated things I had thought about during the 10 seconds she was talking.  This was something that was normal in my life for as long as I could remember, and I just thought it was something that everyone dealt with.  Other people, in my reasoning, had much better self-control and discipline than I did.  Turns out, most other people do not struggle with this.  On the other hand, sometimes it is nice to have a dozen other things to think about when someone else is telling you a boring story.
