Emily Erdos, Harvard, Massachusetts, United States  A map is supposed to symbolize travel, discovery, and possibility, almost all of which COVID-19 has suppressed. I don’t know what comes next, or which metaphorical life turn to take during this time of perpetual uncertainty. As a friend once wrote to me, a map has a quality of authority: Follow the directions, stick to the rules, don’t digress, and you will get to where you want to go. In this time, we all tried to follow the rules, to follow the map, and yet we still got (or are getting) lost in a new normal.  But maps can encapsulate virtual as well as physical realities. They can symbolize home as much as “awayness.” For me, home is a place, but it’s also people. During the pandemic, those people have been spread across the globe, and my only connection to them is through a screen. So my map is a series of mini, virtual, people-centered maps. Knowing that the person behind each map has their own world and journey gives me comfort. Even more so knowing that those journeys, though currently only virtually connected, will physically intersect again someday.
