I know a girl in south carolina who wasn’t from there; she saw lightning bugs for the first time there one summer and she started crying. I find that story very touching- its a reminder not to be blind to the beauty of the world, even if that beauty is so common that it’s unremarkable.
If I’m in an elevator alone with a woman or something I will usually just give a friendly nod and adopt a very relaxed posture, like leaning against the wall. The youtuber Contrapoints talked about this exact scenario in one of her videos (a black man whistling in the elevator so she wouldn’t feel scared) and it made me more aware of it.
