Chimps are not only aggressive but they also regularly eat meat. Mountain gorillas are strict vegetarians. The Rwanda families (I was able to visit five of them in a week) are used to people in small groups. A maximum of eight people get to see them for one hour r each day. They remain inquisitive and sweet in their interactions - you can’t touch them but they can and will touch you. While watching the rest of my group photograph a family I was standing next to a tree and a young female tapped me in the shoulder, stared into my eyes as I turned, and played with my hair. Truly amazing.
