Luna was a little wild orca-boy who lost his family and, after that,
started to look for contact with people which, in my opinion, is the
best example of orca's demand for social intercourse. Just like people.
It's a very important demand for people. And it seems the same important
for orcas. Luna left alone, he was boring, and started to contact with
people. It's interesting how they understand that people (and maybe some
other animals, like dogs) are the same intelligent beings. Amazing is
that even little orca-kids understand and distinguish people from other
beings. Maybe did Luna learned something from his family, adult orcas?
Maybe do they have a sort of lessons like in a school where adult orcas
teach the kids not only rules of survival and hunting, but some basic
knowledge about the world in general? For example, maybe they teach
their kids that people are intelligent beings like orca and it's not
good to attack people and consider them as prey. Maybe, it explains that
there are no any records of attacking people by orcas in the wild.
