My elder teen used the word "self-considerate" (as in her friend wasn't going along with what she wanted her to do but she understood that it was because the friend was respecting her own boundaries) and it is now part of my vocabulary.
I am not being difficult, I am being self-considerate.
After some research (i.e. procrastinating actual work), the earliest usage I can find (and there's not a lot!) is this 2017 self-help book: https://www.amazon.ca/Be-Amazing-Tools-Living-INspired/dp/0998443808
I doubt this is big with the kids these days, but it also doesn't sounds like an entirely new word coinage.
