I received a box in the mail that had no return address. I tried to open it, but couldn't. It was made of some kind of impenetrable plastic. A few days later, I got another box, and this time, same thing, I couldn't open it. The boxes kept coming, usually once or twice a week. At first, I threw them out but then began to stack them in the basement. You never know what might come in handy. After a year, I must have had 50 boxes down there, stacked in neat rows, piled up against the foundation walls.
