Having five younger brothers, Sunday afternoons at our house used to be anything but quiet. After a week of working long hard days my parents both would have loved a nap, but even though we tried to be quiet the noise levels would gradually increase until Dad or Mom would stumble out of the bedroom asking us to be quiet.
One Sunday afternoon before they went to take a nap they set a box on the table and told us we can enjoy the contents.
It was a lot of fun digging through all the treasures inside. There were books, art supplies, puzzles, and some special toy animals and tractors. We weren't nearly done enjoying the things when they woke from a long peaceful nap and announced it was time to put everything back into the box.
The Sunday quiet box became a fun tradition. Books were replaced once they had been read, and occasionally other new things were added which kept that box something to look forward to at nap time every Sunday for years.
