I will never understand sports rivalries.
I will never understand why adults will get so worked up over 'em.
I will never understand why people who have no affiliation with a school (didn't go there, doesn't have immediate family there) will attach themselves so powerfully to a team. People go around wearing sports T-shirts that they bought at Wal*Mart. Is that really your goal? To define yourself as a "Sooner?" As an "Aggie?" As a "Longhorn?" (Although at least affiliation with a college team makes mores sense than the way people define themselves as a professional team's fan. Those teams aren't even regionally-oriented; the free-agent system and the draft system means that they could come from anywhere, and will likely end up somewhere else.)
What just leaves me gobsmacked is when I see that people are getting physically violent over the sight of another person wearing a shirt that expresses affinity for a given ball team.
It's a game. A child's game.
Get over it, folks. Seriously.
