MY HOBBIES / INTERESTS
My name is Luke. My favourite hobby is photography. When I have time I take lots of pictures. I take photos when I’m at my grandparents’. They live in the country, near the forest and have a big garden. It’s an ideal place for me. Sometimes I encounter some animals there. I try totake a picture of them. My Dad helps me to choose the best photos. I send them to magazines. I won a photo competition once. I’ve got a beautiful album called “wonders of the World”. Dad sayswe are going to our grandparents’ for the weekend. I can’t wait! I will be able to take lots and lotsof photos.
Also I have my board games. I can play Monopoly or Scrabble with Dad or Mum. I also have Trivia quizzes or the Millionaire. These are my favourite games that have cards with lots of 8 questions about sport, people and the world around us. They are great!
