On the tenth day of Christmas, my true love gave to me: ten lords-a-leaping, nine ladies dancing, eight maids-a-milking, seven swans-a-swimming, six geese-a-laying, five golden rings, four calling birds, three French hens, two turtle doves, and a partridge in a pear tree!
In the Middle Ages, lords could, to some extent, define the law within their own lands. So the lords are the Ten Commandments.
To celebrate, they suggest having a family game day, including jumping and running activities. I don’t have anyone else at home to play games with, but I can probably jump around a bit. π
