Thanks, Sam - glad you enjoyed it.

You have hit a key point in all this:   When we think we are right and our information or memory is correct, we can all be very stubborn.

Another aspect of this is the tendency to "see" things which reinforce our preconceptions or beliefs, while missing those things which might indicate another truth.  When we want to "win", as you say, we tend to clearly see what will help us do that.

Appreciate your observations:)
