The time of year's coming when I can only go out at night and dream of Yuletide. More accurately, go out at civil twilight because there's no night till August. 20 degrees is my upper limit, and we are well above 20 degrees already. It's not even June yet. But I still feel grateful when I see the weather in most other places in the world. How are people staying alive in Phoenix, where highs in the 30s stretch endlessly into the future, let alone Jacobabad, Pakistan with high of 49° today?
