Is it just me, or is cloudy mornings great? It's not insufferably upbeat and annoying, it's more reserved in it's heat and enthusiasm. It's more of a calming presence that helps me think deeply about the world around me.
I feel the same way about rainy days. People always associate them with depression and sadness, but I've always felt more positive and upbeat when it rains, especially after walking through it. It's like taking a cold shower, it's refreshing and it perks you up.
