Maybe it's a change of perspective, maybe it's age. Maybe winter has become a bit too evocative of what old age would be like- when your spirit is willing, but your body feels half-frozen, fraught with all the signs of physical unravelling. When I was younger, with no friends and no confidence, summer was spent indoors reading book after book. To this day, it's hard to connect with people whose experiences and memories of summer are of easy, physical fun.
I am still resentful of the heat (even if it's nothing compared to the Philippines); the yellowing of the armpits of my white shirts; the constant application of sunscreen; slight twinges of envy when I see fit people. But I smile a bit now when the sun is on my face- acceptance is such a life-altering thing..
