I was very single in September 2012 when NLDS tickets went on sale. Something told me to buy two tickets to Game 5 of the NLDS, though, in case I could find a date in the following few weeks. It turns out I did find a date. My future wife and I went to Game 5 as our 4th date. We watched the entire collapse happen from Section 224. I am still haunted by the image of the Cardinals dugout dancing after Kozma's hit. We watched the bottom of the 9th from the center field concourse. We still kissed at the end of the game (as had been our plan when the Nats were up 6-0) and I was still confident this team was good enough to overcome the gut-punching loss and go to the World Series. I meant in 2013, but close enough.
Update to this: on October 30, 2019 after putting our toddler to bed, I went downstairs to watch Game 7 on TV while my wife went upstairs to sleep. In the 9th inning, I turned on the radio in addition to the TV, which was about one pitch behind. It was a small, handheld radio from Radio Shack (RIP). I watched the TV from the stairs, waiting until the final out was recorded. Then, I ran upstairs with the radio. My wife was jolted awake to the sound of Charlie and Dave calling the final strikeout and telling us to remember where we are so we can remember where we were.
