I used to know this handyman while I was an undergrad at Syracuse University. He was always busy with some project or another. He used to hold up his key ring and say, “Ages ago this ring only had one key. Took me 15 years to get a key for every door in this place. And 30 years more to get back down to these last two. I told my wife, when I get down to one, I’m going to retire.” I’m a grad student. I’m growing my key collection. I figure, why break a perfectly good cycle.
