When I was younger, I used describe the extravagant celebrations that I imagined the fairies were having in the sunset clouds. I explained that their magical parties full of firecrackers and dancing were actually what created the beautiful sunset colors.
Now-a-days when I spot sunset clouds like these; clouds that are shot through with rays of the sun, I always imagine them to be angel clouds. They just seem to embody the light and presence that angels seem like they must have. There's something that feels very right, and very much like a gift for that matter about getting to gaze at sunset clouds like these. Like finding a lucky penny or a beautiful feather or a seeing a shooting star.
