The icing is inside the cake, not outside. Streamers are on the floor. Paste balloons on the stage upside down, with their strings attached to the ceiling. Tablecloths are under the table. Girls ask boys to dance.
Brave guys wear dresses.
On the wall, there is a mural showing dogs walking their people and prisoners arresting their jailors. Flowers on the tables are stem side up. You get the idea. Turn the world upside down and backwards. If you're new to party-giving, this book will be a wonderful way to have your hand held through your first event.
