I like travelling. When I arrive in place, I usually look round a town. Then I'm searching for a place to stay, a hotel for example. After this I buy a map of the place, because I want to see as many sights as possible. I think it's very interesting to visit museums in other counties, go to the theatre, walk in the parks there, to enjoy traditional meal in cafes. At last I buy souvenirs and call my fiends. Usually I have a good time, when I visit foreign counties.
