A weird aspect of my childhood: I brought a sandwich to lunch every day when I was in school. At first, my mom made it, but very quickly it became my own job, not that it was particularly difficult.

The school had subsidized lunches and milk. I always brought a nickel for milk. The teacher collected everybody's lunch money at the start of the day. That way, it was utterly opaque who was getting it for free. A simple system, appropriate for the times.

But I remember that my lunch was always better than the grim school lunch, and I always wondered: Why can't they ditch the hot lunch, and just give everybody a nice sandwich, and a piece of fruit, which is better?

I'm sure there are good arguments for the hot lunch, but still it's counterintuitive to me. And 55 years later, I still bring a sandwich, or leftovers, for lunch, and skip the hot meal at the company cafeteria.
