A
If I were writing a history of my family, some of the darkest moments recorded would be those surrounding Christmas trees．One would certainly think otherwise; selecting and putting up our trees have always been filled with risk．For example, one afternoon dangerously close to Christmas Eve my mother bought what she thought to be a bargain, a glorious tree that was so full and tall that we could hardly get it onto the house．Once we did, my father immediately realized that we would have to hire a carpenter to build a stand for it．Another December, perhaps the very next one, we bought a tree earlier than we ever had before．We were happy with its shape and delighted that its size was manageable．We easily placed it in a stand, decorated（装饰）it from top to bottom, and then self-satisfiedly sat back by the fire in its soft light．Two or three days passed and the truth could not be hidden; we had bought a tree cut so long ago that its needles were coming off．There was nothing to do undecorated it, take it down, and begin treeshopping again．Our most recent Christmas tree offered still another difficult task．When we brought it home, once again it seemed larger than it had in the great outdoors．To complicate matters, we had bought a new stand, one whose nuts and bolts worked more mysteriously than those of our old stand．I persuaded two young neighbors to stop playing basketball and to help us get the tree into the house and set it correctly in the stand．Unfortunately, no one noticed the mud on our helpers’ shoes, so only after removing several reddish brown spots from the carpet were we able to discuss the question of where the lights and ornaments（装饰）were stored．Perhaps those who cut their own trees have tales more painful than these．I don’t care to hear them, as my family’s experiences are enough to cause me to make the following suggestion：“Let’s forget the tree next Christmas．Let’s simply hang some flowers on the front door and over the mirror in the hall．”
