I was having dinner with a friend in the Schlüterstrasse. Around 9 o'clock she looked on her phone and said: "I believe something has happened. A terrorist attack, nearby not far from the Gedächtniskirche."
We finished our meal, then we walked around in the neighborhood. "Everything is so quiet and peaceful as if nothing has happened," she said.
"To act as if nothing has happened is a superb survival strategy," I answered.
