Monta & Momoka sat together at the end of the video. That is what counts. We humans have good and bad days. So do gorillas. I believe gorilla social behaviors are as complex as humans.
I think it is so precious how monta waited for momoka to join him before eating breakfast together!!! he is such a gentleman! he clearly likes having her around, and he's very gentle while asserting dominance over his food. momoka is keep him young and agile by getting on his nerves! hahaha
