Quite recently, she told them in German, at someone’s birthday party, she had gone off by herself in the large house, followed a long hall to a powder room with a full-length mirror extending over the entire wall with the sink. She was embarrassed ("verwickelt") to watch herself sitting on the toilet having a pee. But what really made her blush ("erröten") was when someone -- a BOY -- opened the door and did not see her, no, but saw her horrified reflection ("Spiegelbild") in the giant mirror, and heard the tinkling sound of her urine in the bowl, and her shriek.
It was not until years later that something even more embarrassing happened to her, something too embarrassing ever to talk about.
