We arrived in Washington DC on a Monday afternoon and were excited to see our home for the final month we’d spend in the US before departing for Europe. Shelby parked the car outside of our building as sunlight poured in through the windshield, heating the black leather and plastic interior. When I opened the door, the air was sticky with humidity and the skin of my upper lip and armpits started perspiring. The forecast called for a high in the upper nineties, but it felt hotter.
