I’m reasonably skilled talking to strangers (can last about 3-4 hours in planes/trains/buses if the other party is up to it, after that I usually dry out of conversation), and do that frequently.
However after several years of heavy traveling and hundreds of people talked to, you realize how similar everyone is. It is always the same issues, wife/husband, the kids, the parents…
And it all starts to become a bit superficial. Sure, you can talk, but to what avail? You realize how shallow the situation is because the common ingredient in all stories is that everyone only ever care about their closed ones, which you and them will never be.
And you reassess the book option whose insight or knowledge may very well impact your life much more than yet another seconds to hours long chitchat.
Signed: a disillusioned extrovert.
Signed: an introvert.
So you’re wasting both your time and theirs, for no reasons. Instead, try politely signaling you’re not interested.
That being said, fortunately it’s easy to see people who like to talk.
That’s sad man - I also talk a lot to strangers and yeah most of the time you get average people, but then you meet that one in a million person and learn something truly fascinating or expand your sphere of knowledge or emotion or art or whatever. I’m always on the lookout for the next brilliant engineer, sensitive artist, or just a well read janitor.
