You with the coffee the size of a bucket, we nodded like soldiers

It was minus fifteen at 7am in Lincoln Park and you were walking toward the lake with a coffee the size of a small bucket and ice crystals on your scarf. I was going the other way, shuffling in a puffer jacket like a rolled sleeping bag. We nodded, the way people nod in extreme weather, like soldiers. It was the warmest nod I have ever received. I have been in the park at 7am for six days. I have received two more nods. One was from a squirrel.
