The good news is, the unbearable chill that I'm 70 percent sure has given me pneumonia won't extend into the weekend, though we can all look forward to it popping back up again over the next couple of months. WINTER, WHAT FUN. The bad news is, there are a bunch of subway changes this weekend, so you might have to, you know, walk. Bring an umbrella. Or a baby!
