Post-Christmas Grinch

I've been in a funk for the past few days. I'm afraid I've become a post-Christmas Grinch but I remain hopeful, for this too shall pass. Even the Grinch's heart grew three sizes one day.

And what happened then? Well, in Whoville they say that the Grinch's small heart grew three sizes that day. And then the true meaning of Christmas came through, and the Grinch found the strength of ten Grinches plus two.
