After his busy working day at a plant he arrived home tense, a little nervous and upset, kissing my Mom on the cheek, hugging my sister and me. He rumpled my neatly combed, sparse hair making me angry because I liked to be tidy, and then disappeared behind the door of his study room, not saying a word. We all knew that we should not disturb or bother him at that moment and returned to our school tedious homework giving our fierce-looking father some time to come to his senses. My father was a leading engineer in one of the biggest airplane plants in Moscow. It was an extremely responsible and important job of which he was proud.
