The example of the Nettunfrigorians

There are a lot of things that the Nettunfrigorians don't do over on their distant planet. They don't hate each other, for example. Actually, they don't hate anything. They don't fight, they don't argue, they don't insult one another. They certainly don't kill. They don't drop litter, they don't scrawl graffiti - even though they have four arms with which to do so - they don't even so much as bump into each other on the street and walk off without apologising.

Like I said, there are a lot of things that the Nettunfrigorians don't do.

But this isn't because they are so civilised, so advanced that they have transcended all forms of barbarism and entered enlightenment. No; it is because their scientists just discovered that their sun will explode at some point over the next few months, and this tends to focus the mind somewhat.
