Over our thirteen years together, I’ve adopted some of my husband’s caution around groups, yet the memoir I’m writing contains several distinct groups that form characters sometimes wholly different from the individuals who belong to them. My struggle is how to characterize their communal function and collective personality without doing injustice to its individual members, flattening them unrecognizable with composite characters sent to the page like ambassadors to represent the whole. In a surprising turn for a memoirist, I’m looking to classic Greek tragedy to help me out.
