This is key. Older people do dinner parties. Maybe even with some light board/trivia games or some other activity. If your friends group doesn’t do it, you need to initiate and host. It often takes time to gain speed. Commit yourself to something like hosting monthly for a year. Send the invite a month ahead. Likely someone will offer to host at their place eventually and you can back off a bit. The ball of yarn doesn’t stay wound up without effort, it will unravel without attention and action. Also, and I’m horrible at this, but try to intermix your friends groups. So everyone’s network of friends grows. Also, cheat mode is just organizing dinners out. It’s easier but I think results in less memorable experiences and doesn’t do much to strengthen the relationships of those in attendance.
