Country, where I travelled.
I saw a little sights: restaurant of ice-cream, fortress, cannons and woden ship. It's located in Pafos. I arrived there with my parents. It's beautiful city! People are polite, they try to help you. There is delicious ice-cream. In restaurant you can eat fresh and delicious food. But if you will buy food in supermarket, it will be expensive. Else, there is beautiful and good nature. There is good zoo, where animals stroll in nature. Else there is good teacher of swimming pool. But in one restaurant they cook very bad. Else, one cat went to our house. It ate a lot. I would like to go there again.
P.S. Of course, it's necessary to say, that I spoke English very well. I often spoke English. And they understood me. It's pity, that I have been there only one month. I would like to live there two more months
