There were always attempts at my libraries to set things up - but they kept trying to use hospital codes
My library, when I worked there, had red silken tags at each desk. If you were in trouble, you were to pick up the tag and start waving it around as you talked. Upon which moment, if your interlocutor had not already asked, "Why the hell are you waving a red flag at me?" would presumably be tackled by a gaggle of middle-aged matrons and one elderly janitor. Plus a very nice highschool boy who had no sense, and, uh, me. As a communication system, line-of-sight was a grand idea; as a defense system, ollie-ollie all-come is not all that useful, I think.
I have no secret thoughts about The Secret. Except to say that if I wished death and destruction upon mine enemy, and mine enemy wished same on me, who would win? The one with the bigger brainpan? The one who could stay away wishing longest? What if I need to stop wishing for a minute to pee? Surely the universe understands pee breaks.
About fire -- ugh. Mass. is under fire warning all this week, as our winter was so dry. Which is weird, because it seemed like it rained all of April.
