I am certain the lack of daylight has something to do with it.
Writing dark poetry is easier when skies are gray or the sun has set, so it is no surprise that most of my darker poems were written in the winter months. Weirdly, I also get really upbeat at this time of year because I love brisk air, snow, and the time spent with family over the holidays. Conflicted? You bet! Have I mentioned how much I hate shopping? I hope you too can find some joy in this time of year.
Shopping is better on amazon. (Winks.)
