Brian is a doctor who is usually on time for work, but today he is running late. He is still in bed at 6:30 when he usually gets up, and is driving to work instead of taking the train as he usually does. At 12:00 when he normally has lunch, he is looking after sick patients instead. In the evening, he is watching TV at his usual time of 7:30 before having dinner at his regular time of 8:30 and going to bed at his usual 24:00.
