Well you certainly wouldn't want to put a lump of coal in their Christmas stocking.
Years ago, around the advent of electricity, people simply left their stockings to dry over the wood stove in the kitchen.
Some parents had very little to give kids on Christmas except an apple or an orange or maybe even a piece of candy. They couldn't fill the bottom of the tree. They might not have had a tree at all.
The worse thing you could get was a piece of coal from the coal bin next to the stove. It meant
you were on Santa's "naughty" list and didn't deserve a present. Even rotten kids don't deserve
that horrendous treatment. Bah humbug.
I wonder how many parents actually did that?
As to the green part, pre-dig a hole (if you're in an area where the ground freezes before
Christmas) and plant an evergreen tree. I have a few "Christmas" trees in my yard,
and a friend of mine in Arizona has a yard full of them because she's been
planting evergreen trees for her son since he was born,(as a present) and he's in his 30's now.
And it's a nice tradition too; as the child gets older, they can help plant the tree.
Humankind has not woven the web of life. We are but one thread within it. Whatever we do to the web, we do to ourselves. All things are bound together. All things connect. ~Chief Seattle, 1855
