There's no answer to this, but I'll write it anyway. We say that {-pu'} is to be used with beings capable of language. maj.. But how do we define language ? Words and syllables ? And you now something ? To ghe''or with parrots. They just repeat what they hear. But don't whales and dolphins communicate, or do they make sounds because they just get their kicks that way ? Or because we don't understand their language, we should use {-mey} ? Or should we use {-mey} because they're "animals" ? Because I know many people, myself included, who are waaay less intelligent than a dolphin.. So, I can't understand why I shouldn't say {*dolphin*pu'} instead of {*dolphin*mey}. And because I got so worked up by this obvious injustice to these animals, from now on, it will be *whale*pu' and *dolphin*pu' for me. ~ hkhjhjhj
