One or two of us brainstorm the theme idea and ask the others' approval. One of us finds the place. One of us creates and delivers the invitations. Costumes are encouraged but optional. Cards and gifts aren't required either, but we bring them.
Someone usually brings party favors.
We keep the cost as low as possible, emphasizing the fun of making our own entertainment and just being together. Last year's party, which had a '50s theme, consisted of lunch and zany games at a local diner. It all began with invitations complete with a picture of Elvis. We dressed like the Happy Days cast and enjoyed burgers and shakes. Our antics amused the other customers, whose eyes got even wider when they saw us in the parking lot after lunch, where our bubble-blowing and hula hoop contests capped off another great party.
