Remembering how you fell in love is one of the best antidotes to apathy you have going for you.
Telling that story to someone else brings those feelings back, often as fresh as they were years go.
Invite each couple in the group to tell their story, in as much detail as you can fit into an evening. Invite them to bring photographs, the music, mementos, and keepsakes. Talk about the places, and feelings, the bumps and the ah-has. Be sure to have a box of tissues handy.
