That does sound frustrating @VoluptuaGoodshag. I don't know how you would fix that. Are you at different stages of life? By that I mean do you also have young children & a partner? Or are your children older if you have any? Some times it can just be a mismatch of stages. Perhaps your friend whose kids were distracting her is exhausted wrangling kids, job, family, pandemic etc & just hasn't the energy for deep & meaningful conversations once the kids are in bed?
I don't know, just thinking about it from my own life & how friendships ebb & flow according to other external pressures.
Could you join a club to meet like minded people- book club etc where you might have an outlet for this?
Do you have a partner? Dh & i love to do things like go to a play or exhibition or talk or concert or film & then go for a drink / meal afterwards & discuss it. Pre-pandemic we did this very frequently & we love it. During lock down we switched to films / box sets & books & we talk about them. We love to travel & talk about that a fair bit too, researching stuff, planning stuff it's a huge part of the experience for us.
I'm in a book club which is online now but used to be in person & I adore it. We drink wine but we do really talk about the books.
I read voraciously so I'm always immersed in an inner life & think about what I'm reading through out the day. That sounds pretentious but I had a lonely childhood & always relied on books.
I don't really count school run / vague acquaintances as proper channels for conversations. They're just exchanging pleasantries imo & some people are far better at it than others
The only topic I won't indulge in is talking / gossiping about other people we know. I shut that down immediately. Sharing good news fine - picking someone apart - no thanks! There are a million more interesting things to talk about!
