By early January, I'm generally ready to see the trappings of Christmas gone, especially if they've been kicking around since sometime in mid-November. What's always a disappointment, though, is the concomitant disappearance of Christmas lights and the resultant plunge back into early and unmitigated darkness.
Don't get me wrong: I don't want to see displays of lit-up reindeer or flashing Santas for more than a few days after the New Year. (In fact, I'm not sure I ever want to see such displays, but that's another matter.) What would be nice, though, is if the lights strung through trees outdoors or hanging from eaves could stick around until, say, mid-March, when there starts to be visible hope that daylight will once again last beyond 4.30.
As it is, all of those lights tend to disappear sometime around Twelfth Night, leaving us with what feels like an endless stretch of inky night to contend with.
