At 50, I've evolved into this type of fan.
I've never cried after a Texas loss, or after any kind of sporting victory or failure. (An exception is after my daughter's senior year basketball team lost in the second round of the playoffs, which was the end of her high school basketball career. I went home after the game, popped open a beer, and cried like a bitch.)
I used to let a Texas loss ruin my weekend, and the height of this was the 2008 loss to Tech. I was a fucking miserable little shit for a few days after that, and maybe that irrational emotional reaction is what kicked me out of that level of fandom. For the most part since then, after a Texas loss, yeah I'm bummed, but I quickly shake it off and enjoy the rest of my Saturday with family or friends, or on the rare Saturday evening when I have time for just myself, I'll enjoy whatever is on the college slate that evening. And that's not only during the shitty years from Fuck-You-Pay-Me up to the Horns' recent success under Sark. Even after the Sark Horns' losses to OU, Washington, Georgia, and Ohio State, I've shrugged it off pretty quickly.
And I used to watch the shit out of old games, or after a Texas win re-watch the game that Saturday evening or following Sunday. Now, maybe I'll watch a 10-minute highlight reel on Youtube after a win, or every once in a while go down the rabbit hole of past highlights. But the time I spend re-watching Texas games has significantly diminished.
