Wrote the first real page of the key-and-lock book

Thirty years of keys and locks and I finally put it on paper — not the memoirs, but the part where I realize every guard I knew was an early version of a monitoring system. The weird thing is how gentle the analogy came out. I've been trying to write about automation and control for months and it always sounded bitter, but this afternoon it just read like somebody trying to translate a language he only ever heard spoken. Keys still don't fit, but at least now I can say why.
