Just… Don’t stop? Keep walking. They legally can’t stop you and they know it. It’s a psychological barrier, not a physical or legal barrier. Make direct eye contact, smile, say “No, thanks” and keep walking. It’s worked for me so far.
Not remotely. If you feel like you’ve seen everything, it might be time to consider a (literal) change of scenery. There are too many places to go, different people to meet and try to understand, books to read, flavors to taste. Seeing it online isn’t the same as seeing it in person with your own eyes. You could go a day’s walk in any direction and likely find something you haven’t seen before. You just have to be looking for it.
Humans will take any chance to reduce complex and nuanced psychology into rigid, prescriptive labels. It’s all astrology, only the flavor of the meaningless noise changes.
This is how assholes test your boundaries to see how far they can push you. It wasn’t a joke until you pushed back.
And if my grandmother had wheels she would be a bicycle!
