The cold. I love it but hate it. Reminds me of childhood. My legs can't handle it like the used to. Fuzzy eyes on the bike ride. Numb fingers in thick gloves. Standing while biking though sitting would feel the same. The cold of the metal top tube burning through my pant leg when I wait at a traffic light. But the heart of the apt closes in the moment you're home. It reminds me how I could never live in a warm climate and miss all this.
