Stefan Mehren was enrolled at the Liebfrauen Catholic School in Berlin-Charlottenburg in 1968, where he was taught by nuns and secular teachers. "I had sex education with a nun, Sister Juliane, who stood in front of the class with a red face and let the students say what she couldn't get over her lips herself." He remembers strong childhood images of the street. For example the coal tractors with the box on their backs. Men hammering big hooks into blocks of ice. Horse-drawn carriages with beer kegs… Very quickly he discovered the football field in his area, which was to become his second home. And then later the Olympic Stadium. "My club Hertha BSC has never won an important title since I was born. The last one was in 1931. They became German champions and my father was almost 4 years old. Now my father is 95 years old and he would like to too celebrate a title from Hertha... It can still be."
