In a foggy corner of my mind, I recall reading a book of fables as a child. I'm sure it was old even then. One of the fables told of a poor fisherman (one of the ways you know it's old) going to the 'wise man' in his village to inquire about what to do about his discontent wife: she was very dissatisfied with their tiny, tiny little home and was demanding he buy her a larger house. The wise man told him to keep a donkey in the house, and return in a week to see him. (you also know it's old because the wife didn't pack up and call the lawyer at this point). The next week, the wise man told the man to keep the donkey in the house and add two goats. This continued for a few more weeks until the house was a menagerie of farm animals. The final time, the wise man told the poor old man to take all of the animals out of the house. At this point, the wife was delighted with the vast spaciousness of her 'new' (animal free) house.
I think of that fable every year as we haul the Christmas decorations out of the house. *whew* I love my nice new, clutter-free house. (From December 1-25, they are called "decorations". Starting December 26, it is "clutter", from my vantage point).
Nothing kills any family harmony that may have built up over the holidays like the whole family "working together" to put Christmas away. Not a silent night, holy night.
