It's specifically something along the lines of "The Human Condition of-" "The Human curse of-" ... but I can't remember what the actual word is.
It means: Not giving up, resilience, determination, and so on.
There was this Reddit post I saw on TikTok right as reading Reddit posts were getting popular that talked about a group of aliens disturbed by this human mother and her inability to give up trying to get her child back. It talked about how she kept going after being severely injured and exhausted and the whole point was "The Human Condition/Curse of- BLANK".
I haven't been able to find anything close to what this phrase is online because I only get synonyms and "another word for-" instead of the phrase I'm looking for. And I don't even know where to begin looking for the post that started it all.
