Last Friday, I worked 8 hours on my feet at my retail job in SoHo. As much as I love people, it’s emotionally taxing to be “on” for an entire day with a smile on my face. Towards the end of my shift, I was pretty grumpy. On my train ride home, my grumpiness continued when I realized the train had no seats left. I had to stand for 20 more minutes, shoulder to shoulder with stinky strangers in a crowded little box.
