There are a lot of reasons to enjoy or not enjoy a game. If your team is winning by 10 runs and suddenly drops the ball (sometimes literally) and gives up nine runs in the ninth to almost lose the game, it’s going to stand out. Or perhaps a heroic walk off home run ball landed two seats down from you. Maybe a favorite player signed a ball for you or your excited child.
It could be something as simple as getting to go to your first game at a new stadium, or as bad as witnessing the worst loss you’ve ever seen from your team.
