People that isolate themselves become isolated. I just don’t use a car, but go often with the kids by train to meet other families. We meet strangers and have fun, but sometimes I am lonely anyway. Sometimes in the middle of a chaotic people storm. It’s just what I “blame” it on that is the biggest difference. It’s the way we talk to others, if we are open and if those meet our vulnerability that is the biggest contributor imo. You can never be lonely if someone really cares about you.
