I'd prefer to talk about events or ideas, or activities that interest me. It's far easier to join an online discussion already in progress to feel less isolated in South Bumblefart, USA.
I have found that familiarity does sometimes breed contempt, but absence does not always make the heart grow fonder.
Now, if they want to talk about that time their fighter gutted an orc with an awesome double crit, I’m all ears, but Cowboys losing to some other team in sportsball, not so much.
Some people have uncommon interests or opinions, and may be reticent about sharing them in the absence of some enabling signal, as one can be punished socially just for having them.
It doesn't help that my employer has a mainstream dress code. If I saw an exact copy of myself before or after work, I wouldn't want to talk to it, unless we were in a nerd haven.
I've had too many conversations that bring in early "so what church y'all go to?" or "what's your football team?". The wrong answers can get you a "bless your heart," which seems to be Southern for "fuck off, asshole". Wearing a Chicago Cubs tee-shirt sometimes invites conversation, but my spouse is the fan that live-streams every MLB broadcast that isn't regionally blacked out, and for me it's really more a signal for "I'm from the Midwest." The Chicago skyline on my usual payment card has sometimes unintentionally served the same purpose from restaurant servers and cashiers who are also ex-Chicago-residents.
It's why I'm considering a nerd tattoo, like "e^pi*i=-1" or the Fano plane mnemonic for octonion multiplication, or a space-filling model of my favorite molecule, benzaldehyde.
