Curate, connect, and discover
I grew up in a judgemental household, and have far too many memories of my mother saying "I just don't understand how/why someone would [insert common human behavior she didn't vibe with]." I heard it so often that my instinctive response to that attitude became--that sounds like a failure of imagination on your part. I may not share a person's preferences/habits/behaviors etc, but that doesn't mean I can't accept that such people exist, or exercise my emotional intelligence a bit to guess why humans might make some of the choices they do.
There is, however, one thing that consistently puzzles me about humanity, and that is how so many people seem to actively dislike spending time alone with themselves? I genuinely struggle to wrap my head around this.
