We Are As Mayflies: What, humans?
…well, okay, awesome Sovereign quotations aside, they’re rarely that arrogant. (Unless irritable, and let’s face it, we are kind of an irritating species.) Maybe try:
“Could you at least try not dropping dead all the time just when you get interesting? It really is most inconsiderate!”
…yeah, that might be closer. Anyway, it’s an annoying habit, and we should go consult our nearest space pharmacy and fix it, already. I mean – quoth they – seriously, humanity, your species suffers from a pandemic genetic disease with morbidity and mortality both of 100%, and you aren’t even trying to cure it! Are you all stupid?
(Obviously averted for the eldrae, galari, etc., in-setting, who get to watch everyone else being As Mayflies.)
