I personally have never had the urge (partly because I’m too lazy, and partly because I tend to be claustrophobic). Keith and Carolyn Henson, founders of the L-5 Society (and before they divorced) had tunnels under their house and lot in Tucson, which was quite a feat, considering the hardness of the caliche there.
Many of us frustrated by the lengthy school closures were enraged by a statement we found far too dismissive and even callous: “Kids are resilient.” (The great Mary Katharine Ham tore this apart back in January.) All too often, that was a blasé slogan designed to excuse an intolerable status quo.
Our kids aren’t necessarily resilient, and we didn’t like having their need to be resilient shoved upon them by teachers’ unions who kept dragging their feet on reopening schools and public-health officials who deemed birthday parties, travel, summer camps, visiting grandparents, etc. an intolerable risk.
