The weather seems confused this month.
It rained last week. Water fell from the sky. I hadn't seen rain in months, and was so dumbfounded that it didn't even occur to me that I could stay dry by getting an umbrella. I just walked through the rain and wondered why it was raining in September.
It only took me a year of living here to forget about the five years in Boston, four years in New York, and four years in Zurich (a combined thirteen years, not to mention the nine years in Delaware before that, plus the seven years in Houston and Denver in my earliest, mostly unremembered years), when rain could come at any time of year.
