When you were or are divorcing perhaps you had or have children who were or are 18 or 21 or even 26 or 30. They seemed like they handled it pretty well, but then we can fake it pretty well too. They may have no friends in the same situation, and maybe they would like to meet others who have gone through what they have. Maybe what they are still going through. Let them know about this meetup. It's an opportunity to meet others in a social situation and find common ground and support each other. You can rsvp on their behalf, but mom and dad are not allowed. This is not your mother's meetup.
