A summer evening on a balcony in Cologne. "Actually, we would have to make frozen pizza," says Piet, with black hair, a broad cross and a sip of Gilden-Kölsch. "That would be much more authentic for a shared apartment." Julan laughs. He has tears in his eyes because of the two kilos of onions he is cutting. Piet rubs the gruyere. Instead of pizza, there should be French onion soup - the dish is on a list of recipes that the WG wants to try this year.
