Sleep anywhere…
Be it making a nest, finding a hole or cave to crawl into, or surrounding yourself with pack-mates, all creatures need to feel safe before they allow themselves to fall asleep.
So, for those humans who can just “fall asleep anywhere” I can see aliens being flattered that the human considers themself so safe around them that he/she can just sit in a chair in the middle of a crowded, noisy, room and just fall asleep.
Alternatively… some aliens may be more terrified, as they may think that the human considers them such a non-threat, that they feel safe even when surrounded be potential attackers.
“Human Steve?”
“Sssh, Drblx” – Alice raised a finger to her mouth. “He’s asleep.”
The grklonian eyed the human in question suspiciously. “ How is that even possible?”
“To fall asleep with your face in your breakfast? He’s been up working for over fifty hours, had to pass out at some point.”
“But why did human Steve not retreat to the safety of his sleeping pod, human Alice? Is he that exhausted? Does he need medical attention?”
“Nah, give him an hour and he’ll crawl to the pod on his own. Wait, ‘safety’?”
“Well, I assume you don’t treat each other as a threat, but to allow himself such vulnerability in front of a grklonian…”
Alice snorted. “Drblx. You’re a crewmate, a friend and a ball of fluffy pink fur. You’re lucky Steve didn’t use you as a pillow.”
Drblx, one of Grklonian Dominion’s most seasoned supersoldiers, had never felt so insulted in their life.
11/10 great addition.
