This is heavily paraphrased, but drawn from an actual conversation when I was about 13. This was the year I temporarily
lost my mind and decided I like the Raiders. After being laughed out of the room, my Dad went on one of his infamous rambles. This was part of it:
If you want to know how a man will treat you, you need to look at how he treats sports. This doesn’t count for everything, but it true most of the time. If he plays, does he practice? Is he a good teammate or a ball hog? That’s obvious stuff. If he used to play, does he still love the game or is he one of these cats that just talks about what he used to do? “Oh we won the chip back in 88, I got 35 points” So what? If you don’t watch or play or care about it now, you didn’t care are the game or your teammates, you were in it for the glory, to see who was lookin’ at you. He probably played in school for the girls, to be up under the cheerleaders and wear a jacket. How does he feel about his team? Does he only root for them when they’re winning or switch teams every year? You can’t count on a fair weather fan. If he can’t stand by a team through a rough patch, what’s he gonna do for you? Does he know the schedule or their rivalries? If he doesn’t know that, he doesn’t pay attention. You talk too much to have someone who can’t pay attention. If he doesn’t root for the home team, he better have a damn good reason. Otherwise, he just has no loyalty.
So if you’ve ever wondered why I go in on sports stuff occasionally - I was raised by this man.
