When I was young and starting to dress myself, I noticed an awful lot of my shirts were inside out after they'd been laundered. Since I didn't turn them inside out when I took them off, how they always seemed to get inside out when they came back confused me. Now we're talking about t-shirts and polos--stuff without buttons.
Well, many decades have passed since those days. Alas, I just did a load of laundry and every single shirt was inside out. And I don't turn them inside out when I take them off. What law of physics am I missing? How can this be? The universe is a very mysterious place.
