It was October 21, 2015. The Chicago Cubs were playing against the New York Mets at Wrigley Field, and Marty McFly was intently watching the match on TV, in the living room of his house at 3793 Oakhurst Street, Hilldale. His wife Jennifer Parker was beside him.
Marty reached out for a glass of water. His hand was shaking.
"Let me help you" said Jennifer, in turn reaching out for the water.
"No!" Marty said brusquely. "I can do it myself, dammit!" he added, trying to control his tremors without much success, his eyes never leaving the TV screen.
Marty's hand knocked the glass off the table. The glass fell on the floor and shattered.
"Oh Marty, look at what you've done" said Jennifer, "you should try to accept your condition, and let other people help you. You're just making it harder for yourself."
"Not now, Jennifer" replied Marty. "I'm watching the game. This is important."
The TV announcer was horribly biased against the Cubs. Few seconds later, he was commenting the action that sealed the result for the game: "And strike three called! We haven't been to the World Series since 2000 and the Mets are on their way back!"
On the screen, the Mets were celebrating their victory.
Marty sprang up from the couch. "Nooooo!" he exclaimed, wide-eyed in disbelief.
He stared at the images on the screen. It was all real: the Cubs had just been swept, and would not take part to the World Series.
Marty's face lost its color. He sat on the couch again, holding his head with his hands. "It can't be, it can't be..." he repeated.
"Is everything all right?" Jennifer asked.
"No, no, no... I need to lie down." he said.
"Are you sick? Do you want me to call a doctor?" she asked.
"No" said Marty, "I want you to call Doc."
