When I came up to this gorilla family, he was off to the side, by himself, in his own world. He wasnt the largest silverback but he still had a presence. And then he got up and bent down on all fours and walked towards me. OMG, I was so nervous. He bumped in to me, not maliciously but just to get stay on course for his to keep moving forward. He knocked my kneecap and I was overwhelmed with worry about what would come next. But he kept moving, oblivious to the rage of fear he had triggered in me.
