"Scrooge" does these really material Christmases, perhaps outdoing himself over the years. But he can well afford it.
But Jan 2 always comes.
"Scrooge" doesn't get involved with ghosts, but does actually see what's right around him anyway, and does so as a result of some kind of reversal or confluence of several reversals: finanical, physical, comfort of day-to day.
"Scrooge" ceases to be attached to or lost in Christmas, and is instead generous and compassionate the year round.
