Do you trust the gorillas?
I think a very important rule that I believe any zookeeper should follow is you should never fully trust any wild animal. I would say its much more important to respect a gorilla and it's abilities. If you respect a gorilla's true abilities, as a very strong, potentially very dangerous animal, that's a lot more important than trusting the gorilla. So perhaps on the short term, one might think that they can fully trust a gorilla, but you should never be too sure, because it's always important to remember they are wild animals and they could suddenly turn.
