At the risk of triggering, I have to quote Lewis Black on this.
"Normally, in February, in Boston and in most of the country, the weather is gray, rainy, gray, sleet, gray, rain, gray, sleet, snow, gray; every day it just gets grayer and grayer and grayer! You wake up one day, and you go, 'I'm not comin' into work today!' Your boss goes, 'Why not? You sick?' 'No! It's too gray!'"
"Then you wake up and it's the grayest day you've ever seen! And the next day, it's even grayer! And that's usually Valentine's Day, and that's the day you look at your wrists and go, 'Hey, maybe I should slit 'em to see color!"
