music, so I often attend concerts and go to places with live music. Next to my house is a
cinema, which I visit on Saturday evenings every weekend with my friends. Bus station
and train station are also in the nearing, so I can easily commute to school. In Warsaw
there are a lot of restaurants and café, so you'll never be hungry here. I really like
shopping, so I often buy clothes in very big shopping malls.
Living in a big city also has a few drawbacks. Everywhere is a lot of people,
especially in a subway.
There are a lot of traffics and air is very polluted because of car fumes. There are
also a lot of attractions for tourists, for example build in the 19th century Tower Bridge,
Big Ben and the Madame Tussauds museum with wax figures of famous people.
