On Christmas she'd give the most extravagant presents to them; other times she'd humiliate them, spit on the ground in front of them—once I even saw her spit on one of the workers—break into their cabin and accuse them of stealing and dock their pay. Two researchers left Karisoke because of the way she treated the Africans. ...

The men never knew when she was going to start yelling at them. When she left camp it was like a cloud had risen, and it got worse over the years."
