So, today you wanted to get a drink of water. You went to the kitchen, opened the cupboard, took out a glass, went to the sink, turned on the faucet, and filled the glass with water. The whole process went smoothly. You did not trip on the way to the kitchen, you did not drop the glass, and you did get your drink. But, in another universe, things did not go so well. You tripped, broke the glass, and did not get your drink. Things just did not go right for your doppelganger in Universe X.
But here’s the thing. Something did go right for you in this universe. Aren’t you glad you chose this universe instead of Universe X for a residence? Your thirsty doppelganger is cleaning broken glass from the floor as we speak.
