There is a terrifying moment in a man's life when he asks his wife what she wants for Christmas, and she says the following.
"Nothing. No, wait. A vacuum cleaner."
Oh, no, it's a trap. Surely you know how this will turn out.
Wife: "I'd like a vacuum cleaner."
Husband: (Researches the best options, buys the state-of-the-art Dysharkoover 9000, sticks a bow on the handle.) "Merry Christmas!"
Wife: "How could you?" (Leaves room in tears.)
I agreed with her that it was time for a new one. The old one smelled of burned dog, and compared with the new models, it had a rather Soviet heft.
It lacked a headlight, and those come in handy when you want to find dirt hiding in dark places that you'd never vacuum, anyway. But who knows; houseguests might drop to their knees with a flashlight and look behind the sofa, so you want something with the candlepower of a movie premiere searchlight to find those 16 atoms of dirt.
