"When I got to Rwanda, Dian was extremely warm, welcoming and encouraging. She was also a bit scary, exuding a determined, uncompromising, take-no-prisoners attitude towards poachers, cattle in the Park illegally (of which there were many at that time), and any ‘students’ who didn’t dedicate themselves 100% to the good of Karisoke. Basically, she appeared to fear nothing and was not going to take any nonsense from anyone. At the same time, she seemed like a very emotional person, almost too emotional."
