There was a time when I used to be a bit precious about The Tree. It had to be the bushiest, biggest, most Christmasy tree I could find. Then, decorating it, white lights only. Pretty, co-ordinated decorations. Nothing too gaudy or clashing.
And then I had kids.
This year, the boys decorated our tree. (Kindly sent to us by Pines and Needles, this lovely Nordman Fir shouldn't drop its needles which is a blessing.) They went nuts with the decorations, putting everything they could find on there, including their own homemade cardboard alien decos.
