I woke up late and had breakfast in a hurry. I had never been late and didn't want my boss to be unsatisfied. However, it seemed that day wasn't a lucky one for me from the very second I left my flat. The moment I wanted to rush downstairs one of my stiletto heels   broke. I had to return to change my red shoes. I also had to change my purse and other little things that I had tried to match with the shoes. I was sure I would be late for work. On my way to work I had to wait for over half an hour because of an accident. I had no choice but to wait. I phoned my boss and he told me that it was no problem, but he needed me for the meeting with the Japanese clients   that morning. Finally, I arrived at the office one hour later. I had to keep calm and be fresh for the meeting to make the clients sure that our plan was the best for their future commercial   project. However, I left the plan I had made the night before at home and was going to present   it to the clients. I was about to get angry when I realized that I had a draft   of it in my office. At last, the presentation came to an end and it turned out to be a success. But I have to say that I had a terrible day, full of incidents  . Which of the following is NOT the reason of the writer being late for her work?
She got up late in the morning. She changed her purse and other little things. One of her shoe heels broke. She had a traffic accident on the way to work.
