One day Susanne did not show up for work. She had not called in sick nor did she take a holiday. I was quite worried that something had happened. I called her, but there was no answer. After work, I drove to her place. The lights were on in her apartment. I rang the bell, but no one answered the door. Finally, after I repeatedly rang the doorbell, Susanne shouted from within, “Who is it?” I was relieved to hear her voice. Hesitantly, she opened the door.
