Imagine you are playing an important game of tennis. It’s the club final and you are the favorite to win. There is a big crowd watching and as the game progresses, everything seems to be going to plan. You’re playing well and you’re winning points. Victory can’t be far away. There is only one problem: there is no scoreboard, and the umpire is keeping the score to herself. So no one except the umpire knows what’s really going on.
Nevertheless, you plough on and, despite being in the dark about the score, you feel positive that eventually the umpire will declare you the winner. You are so confident that you can’t help but relax just a little. You start enjoying the party like atmosphere.
