Humans having the incredible ability to fall asleep pretty much anywhere. So long as isn’t actively on fire or made of broken glass and wasp stingers, it’s good enough for a human to conk out on. It not exactly good sleep, but it’s sleep either way.
Which is very odd to the galactic community.
Rest comes in all sorts of forms across the galaxy, some having sleep similar to ours, some having hibernation/brumation cycles, some going into meditative states, some retreating to cocoons, some photosynthesising, some even being technologically advanced enough to simply just plug themselves in and literally recharge. But the seeming inescapability of human sleep is…a little concerning.
If a human is tired enough, they will be able to sleep just about anywhere. Bed, sofa, armchair, the floor, a table, three chairs lined up, propped up like a doll against the wall, on top of another person, on a rock that’s even vaguely flat, on a gnarled tree branch, sometimes even floating in water or suspended by a harness. Wherever. So long as we can breathe, we can and will fall asleep.
The same can’t be said of aliens, they’re a bit more picky by comparison, or they can stave off their exhaustion through emergency chemical reactions long enough to find somewhere appropriate to rest. Some are so specialised that they require their environments to be utterly perfect before their body allows them to rest. Those aliens are deeply jealous while waiting around at the Spaceport for their shuttle to start boarding and seeing humans clumped together on a bench in a very uncomfortable looking pile, snoring away.
And then, an alien species named the Khak’Cthrax, a species known for their aggressive behaviour and bodies covered in rocky scales and dangerous barbs, discovering this aspect of humans.
One Khak’CThrax soldier being deployed to assist in saving some human civilians from a war zone and ending up having to carry a teenager for a while due to there not being enough gurneys. The juvenile human ends up nodding off in the soldier’s hands and at first he thinks the teenager has perished because the Khak’CThrax are not the type of person you would consider comfortable to rest on much less feel ‘safe’ around inherently, but after the field medic explains that the child is only asleep, unsurprisingly from the day they had had, the soldier practically becomes a broody mother hen for the human. This little one trusted him??? Enough to rest while held in his arms??? They are his baby now???
Made worse by the fact that humans are half the size of the average Khak’CThrax when fully grown, so a scrawny juvenile was practically the size of a newly hatched whelp to the soldier. All tiny and soft and squishy. The soldier nearly took another Khak’CThrax’s arm off for trying to poke his new human baby.
