At St. Lucy School in Raruowa, Nairobi, Kenya, Sister of St. Francis of Philadelphia Frances Cassidy has the usual tasks and challenges of a teacher and principal, But then there a few that your average teacher doesn’t have to deal with, like dealing with rats in students’ lockers or snakes under their beds; cows giving birth outside the school; or people trying to break into the dorms at night. Add the fact that money and water sometimes runs out and end-of-year chores such as clearing fields and gathering stones to fill in the rutted road, and Cassidy has a full-time vocation.

Mission work sometimes puts people in challenging situations. How would you react to some of the situations Sister Cassidy faces?
