In religious life there are certain rules that are neither written or ever spoken, but which--at least in my experience--are universally observed. Sometimes the strictness and regularity with which they are observed can seem inversely proportional to any imaginable utility. For example:
In religious life we tend to have the powdered sort of laundry soap, the kind that comes in a big box. In the box comes a little plastic scoop by which you are supposed to measure the soap into your wash. Here's the rule of religious life: when the box becomes empty, it is thrown out, burned, or recycled, depending on local law or custom. The plastic scoop, however, may not be thrown out, but must be placed into the next, newly opened box of soap.
Never mind that the new box comes equipped with its own scoop. Now it will have two. When this box is empty, its two scoops are transferred to the next new box, which will then have three. And so on. I have observed the results of the careful observance of these procedures in every friary to which I have ever been assigned.
I don't know how to process is interrupted, but I have seen as many as six scoops in one box of soap.
