Some days feel a little off-kilter. Nothing you can put your finger on. The shower doesn’t get hot fast enough. It’s cloudy when you’re wishing for sun. You look at the clock too often, acutely aware of how long it takes to get from 2:30 to 2:40.

Other days are the opposite. You catch the subway seconds before the doors close, every time. You feel buoyant and chatty: The cashiers all smile at you. Your coffee tastes better than yesterday. The pear sitting on your kitchen counter has ripened perfectly, dripping juice down your fingers when you eat it outside in the sun.
