Last weekend I did an evening run. It was chilly and damp. I wore shorts with a long-sleeved thermal shirt. It was just about right. I definitely needed the insulation.
I came home, and shortly after that the power went out. We lit candles, including putting a tea-light in this thumbtack-pierced spritzer can that Sophie had made. It was still dark, and it was chilly, so we actually lit a fire in the wood stove. In July!
Then, over the next 24 hours, summer finally showed up. In the past few days we've gone from quickly closing the door to keep the 12ºC chill out to quickly closing the door to keep the 32ºC heat out. There seems to be no middle ground at all in the weather this year.
