Thursday. We wound down the last shipping day before Christmas, taking orders up to 2pm, shipping out 2,000 boxes. As the building emptied of food and treasure, once invisible things returned to view. Like signs. Every business has them. There are the "Please!" and "Don't!" appeals meant to save you from a terrific accident. There are the location signs that let you know It's OK Dear, You're in the Right Place. And there are my personal favorites, the arcane checklist and process signs that make sense to locals only. Out of context they read like poetry.
