Sissel and some guy singing Simon and Garfunkel’s “Bridge Over Troubled Water.”

That song always takes me back. I remember a night in college, when a friend was leaving because he’d flunked out (turned out in the end he had a learning disability). We took him out to our favorite haunt, Mitz & Bert’s diner in Lake Mills, Iowa, where you could get a tremendous hamburger and a big plate of hot-enough-to-burn-your-mouth french fries, plus a chocolate malt, for $1.03 (I had to watch my dollars in those days, so I remember). Before we broke up for the night, somebody played this song on the juke box, and it was like a benediction.

That was some time after my high school graduation, which is on my mind because we’re having a sort of informal class reunion this weekend, down in Kenyon. Every molecule in my body is screaming, “DANGER! STAY AWAY!!!!!!” but I guess I have to go, because I missed the last regularly scheduled reunion.

I’ve never understood why people invite me to things, or register disappointment when I fail to show up. Is it my unsmiling, expressionless face they miss? The way I sulk in the corners and avoid eye contact? My bitter, self-pitying jokes? Or my early exits with lame excuses?

No wonder I can’t talk to people. They’re strange.
