Hi yes I was in the bookstore only a couple minutes and got one book about the history of packaging that promised, among other things, to reveal the secret meaning to cans and tubes, and another book about sand and how it transformed civilization but in my defense if you ask, "who do I know who would buy a 300-page book about sand" you would answer me. Or @Azure. Maybe @zebratron2084.
@Felthry Right? I also considered very seriously but put down a biography of Jean-Paul Marat, and another one about Einstein's interactions with Henri Poincare's theories of mathematical physics. (In fairness, I read that one decades ago.)
