I can't remember the specifics (both because it was dumb and because it's so embarrassing I think my brain is trying to protect me), but from what I recall I got into a heated argument on the internet with someone because I felt that fans weren't cheering hard enough for a band I liked at a concert.

...yeah, I know. I'm grateful, though, because it was so colossally stupid and pointless that I had a come-to-Jesus moment and swore off internet arguments entirely. I can only imagine the countless hours of my life it's saved me in the intervening years.
