Having left my rural Missouri home to serve as a Peace Corps volunteer in Guatemala from 1988 to 1991, I felt a visceral connection with the 169 volunteers preparing to leave Guatemala on Wednesday. They shared personal stories and photos on social media, trying to come to grips with what it means to be evacuated from the schools and host families and wider communities they were part of. As they said their goodbyes, I imagine every one of them pledged to return. One day they will.
