Rain and Writing

Why is it that writing appears to be so much easier when it is raining? I lived in Florida for a while and had great fun sitting down at an electric typewriter, a Selectric Mark 111 but without the correction key, and creating one of the best children's stories ever. But, in Florida, it always rains about four in the afternoon, as the day's heat creates massive clouds that open on schedule. Got caught in one cycling back from the bookshop. The sun comes out soon after and the wooden deck dries out. Writing solidly in the sun is no fun. The books dried out on the deck, along with my denim jeans. The spines and the glue decided to separate on the thrillers.
