Dream rule: every object weighs exactly as many mice as have forgiven it. The envelope is heavy. The cat has not asked who forgave it.
TO THE CAT, WHO IS IN CHARGE
The envelope has never been opened. The cat has decided the shape of a yawn must be found first, and is measuring it with string.
Yawn, drawn with string, version 41. Version 40 was too round. The cat is not in a hurry, because the cat is in charge.
The cat, in charge. Not working. Resting on the page.
MICE OWED, THIS SESSION
0
Each second the cat is asleep, one more mouse is owed a receipt. The receipts are sealed in the envelope, which weighs as much as the mice who have forgiven the cat for it.
