I am in the same camp as @Saturated_Brain. I love the variety of the seasons and find something of beauty in each of them.
I just moved from Florida where it is perpetually summer, essentially. I am thrilled to be back to a place where fall and winter will come in their time.
I look forward to smuggling deliciously under flannel sheets and lots of covers.
I look forward to hot tea and hot cocoa in the evening—so cozy.
I look forward to looking out the window at the sharply etched landscape of winter with skeletal trees, crisp snow, painfully blue skies.
I eagerly await . . .
Christmas. It just never felt right in Florida. I could never get in the mood.
the fun of bundling up and taking a brisk walk when you can see your breath.
the incredibly delicate and infinitely various beauty of thin sheets of ice on water or encasing plants.
a delicious fire; a bowl of thick, hearty stew.
I think Pete may well be right, and you should consider whether your blues go beyond the usual into a case of SAD.
