My father is 73 and has decided to retire. We are having a casual party for him and his friends at his house....he just doesn't know about it! My mother is in on it. Do you have any ideas for decorations, activities, etc.? I thought about having one of those big desk calendars around for people to fill in with ideas to keep him busy (ceremonial burning of the briefcase, sleeping in, early bird specials, senior day at certain stores, etc.). They can be joke or serious things. All ideas are welcome! We have one month!
