This is precisely the same as the cat calling mouse.eat().

Note that it is getting a completely new object.

It's private peeking is 'ok' since it shares that private knowledge.  It
doesn't make it good though.

They can invoke any of the PUBLIC ENTRY POINTS, yes.

But you can't call store.parent_class.connect(on the transport), since
they are not the same object.
