Yes, many times.
Many times, for the 20 year I worked International, on long haul International Flights while seated - I would usually always say hello to the seat mate and we might talk or not. Had some very interesting talks - some of the flights was 12 hour so....
In retirement I still will talk to folks nowadays but it is not as much as in years before. Alot depends on where the encounter occurs, e.g., in a grocery store shopping we visit regular with folks vs a guy coming up to me while I'm pumping Gas - not so much, and Texas is an Open Carry State...so there's that.... ha !
I was and am careful about what I would share with folks.
