Ever lost an argument, only to realise hours later what you could have said?

Happens to me all the time.

But I choose to believe that I don't have the natural ability/tendency to disregard the argument of others and defend my own judgement blindly, but instead think through the validity of the other party's point of view before firing a stubborn statement. :)

Too bad, I think the world is made up of the other kind of people.
