I don't know what it is, but this time toward the end of the year has always felt to me as if it operates in a time frame of its own. Time slows down, and flows at a different rate, and in variant channels.
It begins for me several days before Christmas, and continues on through New Year's Day. No matter what I'm doing, no matter what my schedule. Time stretches out and distends, as if time itself drifts off into a realm beyond time.
