Just over a year ago, I was asked to visit a kindergarten classroom on the Northwest side of Chicago. The purpose of my visit was to join the class and to pay extra attention to two twin sisters from Burundi. The girls were a source of constant stress for their compassionate teacher, Miss Chavez, who suspected that they were utterly lost during instruction. She reached out to the community center where I worked, who sent out a call for anyone who could talk to the twins in Swahili or Rundi–the languages spoken by their family at home–and assess how much they understood.
