When I was a kid, my father had an ongoing joke every. single. year. He threatened to paint a Christmas tree on a white window shade* To decorate the tree, all you had to do was grasp the bar at the bottom of the shade firmly and pull down. At the end of the season, grasp the same bar, give a sharp downward tug and let go and the shade would roll up.
Needless to say neither me or my sister thought this was funny. And every year Dad stuck a real tree in a stand. In later years they were trees in pots from the nursery which were planted after Christmas in the back yard and all died about two months later.
Maybe this suggestion that real trees were a lot of work when brought inside the house has stuck with me. Or maybe I’m just fundamentally lazy. But a real tree has not found its way inside my house since I left home.**
