When Mirzana Coralic asked the primary school in her Sarajevo neighborhood whether they would enroll her deaf son, teacher Sanela Ljumanovic volunteered. Then September came and 6-year-old Zejd was there, silently sitting on a bench, his eyes wide. No one at the school, not even Zejd, knew sign language. “We have to come up with something here,” Ljumanovic remembers thinking. She tried to develop her own tricks to communicate with Zejd but a parent proposed that the whole class learn sign language with him. Three months later, the first-graders of class 1-2 at Osman Nakas primary school have mastered the basics of sign language to communicate with their classmate.
