That’s a reasonable idea, and we have tried. We let them know about favorite artists here, interesting events; we have a great botanical garden with a fabulous kids’ section. We asked and invited , casually ("hey, if you are looking for a day trip ") and specifically (“would you want to come to SomethingFest with us in May?”) . They never take us up, and over time we took the hint and stopped asking.
I once got them to agree to a long weekend at a shared house, they liked the idea, we gave them dates to choose, they did, I booked the place, shared the good news – they said oh, we can’t go, didn’t know you were serious.
That same spring, they drove 6 hours to hang out with their friends. I’m not a genius, but I understand the messaging.
