I have a MI/NU story.
I lived in the Ann Arbor area for 3 years. I had a very nice 80 yo neighbor called Roger. He loved football and, weirdly I thought, he loved hanging out with me. I was 29 when we met. So we went to 2 or 3 games together.
At a point he surprised me as he had bought tickets for the game against NU. It was snowing that day. Stadium was still like 1/2 full at kick off. It was windy, snow was blowing, drifting, it was creating a slush against your clothes... We decided to leave at half time. Stadium was less than a 1/4 full at that point. Roger waited at the door as I walked 10 minutes to go get his tiny car. He could not walk, let alone drive, he was too cold.
I saw the end of the game at home, NU won. Few weeks later I learned Roger, as a result of going to the game, had been pretty sick for two weeks.
I felt I almost killed Roger. Like a willing helper to his 2 packs of ciggies a day.
Roger died a couple years after I moved. His son was kind enough to let me know.
