After a few black mornings in the single digits Fahrenheit, I thought I’d have a great shuffle today with temps in the high 30s. Instead: worst run in ages. You can usually just push through to some rhythm and comfort—sometimes even an especially great run, but today I was grumpily back inside in less than 25 minutes, tail pretty firmly tucked between legs. My fallback position at times like this is what I think of as The Full Scarlett—“Tomorrow is another day!”
