Subject: Dear friend
… My older brother has decided to collect mugs, imagine that. He has already got eight mugs from different places he has visited. It’s a nice collection but it takes up so much room … Why do people collect things? What do you collect or what would you like to collect? What other hobbies are popular with teenagers in your country?
Write a message to Ben and answer his 3 questions. Write 100–120 words.
