Помогите пожайлуста с переводом на русский: Buddy thought he was going to die when his dad came downstairs ready to go at six-thirty. He was dressed in his complete Teddy boy outfit: drainpipe trousers drape jacket with velvet collar bootlace tie thick crepe-soled shoes and fluorescent green socks ... it was clear that he`d taken great care to look as tidy as possible. he`d dressed himself in his "best" for the occasion. "I thought you had to go straight out afterwards," Buddy said, not daring to come to the point but hoping his dad might change his mind and put on something else. Jeans - anything would be better than this. "I am. I`ve got my other stuff in here," he said, holding up Woolworth`s plastic bag. Buddy`s stomach turned to water and he felt sick. The evening was going to be a disaster. "Dad," he said weakly. "What ? " "Can`t you put something else on?" "Why?" "Well, it`s just ... Mr Normington won`t like it." "He`ll have to lump it then, won`t he?" There was a touch of sadness in his dad`s voice, and Buddy knew he`d hurt him. The walk to school seemed to take ages. His dad was right . What did it matter what Mr Normington thought? It wasn`t as if his dad looked scruffy or dirty - he looked really smart. But he did look different. Even some of the people in the street looked twice as they walked past.
