IDEA: extrovert train carriages. Like those ‘chat to me’ benches, but a whole carriage of the train dedicated to people who wanna talk rather than just read a book or listen to music (through headphones, of course) and enjoy the scenery. Introverts can drop their extrovert mates off in those carriages so they have people to chat to, and extroverts will leave us alone to enjoy our quiet time.
Extroverts do this ‘I’ll keep you company!’ thing at really distressing times imho. Like, just as I’ve managed to extricate myself from the group and I’m getting ready to go out for a walk, someone will go ‘I’ll come with you!’. Oh noooo I’m only walking to get AWAY from people! Or I say I’m nipping to the shops or out for a vape ‘I’ll keep you company!’ - I don’t WANT company that’s why I’ve found an excuse to go away!

@girlonthenet I read somewhere that one of life's sadnesses is that introverts understand extroverts better than thr other way round.

One of my nicest experiences at one job was when an extrovert colleague thanked me for coming with her on her sandwich run one lunchtime because she recognised my sacrifice of solitude. (She was a good egg, and worth it.)
