being an introvert doesn't make one boring. if you have any shared interes with your friends whatsover, there is a seemingly infinite amount of stuff to talk about. many people just have a hard time talking about specific subjects, or making specific subjects relatable, mostly solitary ones like reading books, watching movies, playing video games and similiar activities. it seems they do not make good material for discussion, but that's just not true, it's more of a defensive action because most of these activities are still (only to some degree) stigmatized as being boring, and therefore many people are afraid to talk about them passionately.
from my experience if you are passionate for literally anything, and have even the slightest degree of eloquency, you can make your passions sound interesting. even if it's something hyperspecific like sub-saharan geopolitics in the late 20th century, or a new farm simulator that just came out. admittedly some things are hard to convey via language, e.g. the feeling you have while reading a really good book, but I think that is mainly due to our constrainments.
tl;dr: talk passionately about what you like, no matter how "weird" or boring it might seem to you (unless it's something actually detestable, but I doubt most of the people here spend their free time torturing or smearing their walls with bodily fluids)
for me, leaving out all the screen-related activities because that's just way too much to list, I cook and eat out a lot, I like going to the theatre or cinema, I do some weightlifting, I read a lot of books and listen to records, I write sometimes, do some basic gardening, I very much enjoy grooming, doing dishes and often play table top games with my love. also I really like doing lists, this one wasn't as fun though.
When I was single I hated just "going out." You'd spend a bunch of money to go to a bar or club that was way too loud to really engage with anyone and just sit around drinking, waiting for people to notice you or go talk to someone, but it always felt like a colossal waste of time. I'd be sitting there with my buddies, not saying anything cus again, noise, and thinking man I would be having way more fun just playing world of warcraft right now.
You. I like you.
Also, in reference to my above post: Look how attractive civvver makes playing WoW on a friday evening sound. makes it sound like doing lines off the back of a hollywood doll. with a side of glazed cherry on a paté served on a filet steak. funny, totally relatable, could be told in almost any informal setting and would get some smiles (from other gamers at least ). tell it in a self deprecating way and people won't even know if you really meant it or not
Most people I've talked to don't have terribly fascinating private lives. It's just that some people are better at dressing it up to make it entertaining.
yes, exactly that. or they filter all their activities and only talk about the ones they think are prestigious/exciting/portray them in a certain light/make them seem more interesting.
