That's what makes this all interesting. I don't find Seattle winters in the least dreary--I find the weather pretty energizing. And it really isn't "sunless". It's grey often, but sunny days get interspersed in there. I like it a little cool, and I hate humid heat and relentless sun. So it's all pretty idiosyncratic---one person's dreary is another's pleasure.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
