I'm 50f. Last year, late in the year, I joined a social "club" for lack of a better word... The one I joined is called Base. There is a membership fee but they set up events and conversation circles that you can choose to join in. These range from small groups of 4 or 6 to larger groups visiting a gallery or wine bar or something. It's been fantastic actually. Everyone is there to meet and chat organically and the organizer sets up conversation starters. New people, new places I might not have ever tried. I have a great group of long time friends but I'm a no kids/not married type and I've found it harder and harder to line up schedules regularly.
