My sister was driving the biggest FedEx truck I had ever seen, naturally and with confidence. I decided to come to work with her that day because I wouldn't see her again for a while. She was driving and I was stationed on top of the truck. It was like being on a steamship, on the lookout for icebergs. High above the street I could see for miles but despite the distance I could easily hear my sister talking about her life. Her job, her relationship, her home. She weaved with ease in and out of traffic, her tires were larger than a monster trucks, and even though I had anxiety I could tell she knew what she was doing.
