Humans are adorable.
Supporting evidence:
1. Humans say 'ow', even if they haven't actually been hurt. It's just a thing they say when they think they might have been hurt, but aren't sure yet.
2. Humans collect shiny things and decorate their bodies and nests with them. The shinier the better. although each individual has a unique taste for style and colouring

3. Humans are not an aquatic or even amphibious species, but they flock to bodies of water simply to play in it. They can't even hold their breath all that long; they just love to splash!
4. When night falls and the sky goes dark, humans become drowsy and begin to cocoon themselves in soft, fluffy bedding.
5. Some humans spend time in each other's nests! Just for fun! It's not their nest: they're just visiting each other.

6. Some humans use pigments and dyes to make their bodies flashy and colourful! They even attach shiny dangly bits to their cartalidgous membranes!
7. Humans are very clever and sometimes adopt creatures from other species into their family units. They don't seem to notice the obvious differences. and often raise them alongside their own young!
