Better than plastic.
Always better to see further than fashion and connect/smile with (non-aggressive) people, even if you personally don’t like their clothes/drinking vessel. I use a military flask but I’m not using it to look military. If I was, I might still be a nice/interesting person.
I think it is possibly a trend nowadays to talk quite badly of/ridicule strangers who follow any fashion except one’s own.
Trying to think how I’d feel if some stranger took enough interest in me to photograph me in my Crocs with my flask for public ridicule? I wear them because of metatarsalgia, but my persona would prob be mostly the same even if I wore them because I liked the shape or colour, or because my mates did? Maybe not. All very confusing, I wonder what Spock would say?
