Inspired by an incident with just such a person. It also reminded me of some indie comic book in which the main character gets a negative reaction in such a situation (he’s the one talking to someone else), and gets snippy, along the lines of “well, excuse me for trying to engage in basic human social interaction!” (I don’t remember how, but basically “shaming” the other party for being rude and antisocial for not wanting to listen to him; I wouldn’t be surprised if this was meant to be hypocritical and/or ironic).
How do you deal? How open are you to engaging with complete strangers, assuming you’re in a setting and mood where you don’t particularly want to engage?
