During the last 18 years, it’s likely that a few dozen people helped you raise your kid — and you may want to invite all of them to the graduation Decorations party. Just remember that the party is first and foremost for your child, who may want to invite all of his friends. Come up with a maximum number of people to invite, and allocate at least half of those spaces to your grad. My parents actually hosted two small graduation parties for me — one for family and one for my close friends.
