Maria is a teacher. She works in Sofia, at a school on Vitosha Street. She is not happy at work. She is going to quit her job in June.
After that, she is going to travel. In July, she is going to visit her friend in London. Her friend lives in a small flat on Baker Street. They are going to meet at the airport on the 5th of July, at 9 o'clock in the morning.
After London, Maria is going to study French. She is going to start her classes in September, at a language centre in the city. She is very excited. She says: "I am not going to work at a school again. I am going to do something new."
It is Saturday morning. Tom is at home in his flat on Green Road. He is going to have a very busy day.
At 10 o'clock, he is going to meet his friend Jake at the gym. The gym is on Park Street, on the first floor of a big building. After the gym, they are going to have lunch at a café in the city centre.
In the afternoon, at 3 o'clock, Tom has an appointment at the hospital. His doctor works on the second floor. In the evening, Tom is going to go to a party. It starts at 8 o'clock. Tom is not going to stay late because he has work on Sunday morning.
