Throwing a birthday party for a 7-year-old:
Build a treasure chest. Purchase/collect/create treasure to fill chest. Bury chest in friend’s backyard. Write clues on parchment paper in “pirate” script, hide around neighborhood. Bake a cake, frost and decorate. Sew many black eye-patches. Cut out pirate sword shapes from cardboard; purchase paint and decorative items for them. Sew pirate “booty” bags.
Escort swarm of kids through clue search and follow, digging up (in the rain) of muddy chest, opening and distribution of loot. Feed kids cake and ice-cream. Manage mass chaos of decorating pirate swords. Open presents.
Throw out wrapping paper and detritus. Wash clothes muddied by treasure chest excavation. Wash dishes.
Throwing a birthday party for a 15-year-old:
Hand kid $50 to feed him and his horde of friends. Wave good-bye as they disappear into the night.
