Personally, I don't mind the rain. The grey sky is easier on my eyes, the humidity is easier on my sinuses, and it even seems that outdoor noise is more muted and kinder to my sensitive ears.
Maybe that has something to do with the fact no one mows in the rain. Or hammers shingles for a new roof. Or does other construction or destruction or road work or even plays outside. There's just the raindrops on the roof and the deck and the warm asphalt and the grass, and the splashing of vehicles in the roadway.
I'm sure if it rained a higher percentage of the time, the grey and the wet would become oppressive. And I know that the damp days are hard on those with arthritis, fibromyalgia, and shattered bones that are healed but not properly so, and as we have family members with all those things, it's hard not to feel a little guilty at enjoying the rain.
But for me the rain is a relief, and I do not begrudge the people who enjoy sunshine their sunny days.
The rain can also make for some lovely photographs.
