SPIEGEL: Why do we dress up and what is a good costume? How do our children become happy people? And what role does the choice of secondary school play in this? I ordered 100 modeling balloons online this week: 50 in tropical coral and 50 in bubblegum pink. I will use them to make a carnival costume with my ten-year-old son.

He wants to go as a sea anemone. For the sake of variety, I talked him out of being a Death Eater: "It's better to go to carnival as a billionaire, child!"
