At least my window opens

I'm in my office, looking outside at the sunny 15°C day and—oh, dear, I must be coming down with something, perhaps I should go home and rest?

Chicago was last this warm on November 10th, when it got up to 17°C. That was four months ago. Four. Months. One hundred twenty-three days.

*cough*

Yep, definitely too sick to stay in the office now...
