Yknow now that I've talked about it a bit, TFA cybertron doesn't actually HAVE a concept like "parenthood" does it?
I mean, they have a concept of, like, rearing, and teaching young bots but that seems to be purely in the context of education. The farthest you get is something like a caretaker which doesn't necessarily denote an emotional connection.
OP and co didn't quite seem to understand what a 'dad' was when they arrived on Earth though the fact that they quickly picked up on its meaning probably means they understand the concept at least emotionally.
I dunno, I'm just thinking a lot about how, like, on Cybertron plenty of bots probably ARE like parent-child relationships but don't have any kind of special name for it. The emotions are there but there's no inherent cultural structure backing it up.
I'm just wondering what kind of implications that would have for their culture as a whole and what being introduced to the earthen concept of "parenthood" might do.
