I like shopping. When I really need something, I go to the shops. For example, it is funny and enjoyable to choose clothes. My clothes represent my personality and mood. Usually I ask a shop assistant about the fashion things, colours, size. When I choose something elegant or cool, I go to the changing room. If it suits me well, I buy it by card or in cash. Also I like bookstores. I can spend hours walking along the shelves with books. Sometimes I go to the flea markets. There are a big variety of souvenirs, gifts and other interesting things.
