My DH and I will be married 50 years in November. We are hosting a luncheon for family and a few close friends. Will be held in a restaurant in our area. We do not need an gifts and don't want our family members to feel an obligation. (some really can't afford to spend the money) What wording can we use on the invitation to say that. I was thinking something along the lines to say no gifts, please come and share a special memory of time we spent together.
