Let me tell you about my hometown. I live in Kinsale. It may be one of the smallest towns in Southern Ireland, but it is also the most famous one. The fish restaurants are very wonderful and there are many good cooks here. They cook the best fish for the visitors. The food is expensive but people enjoy it very much. So you can see many people from different countries in every restaurant. My town is very beautiful because it is by the sea. In summer it is very cool and you can go swimming in the sea. There are three small shops and you can buy your friends many souvenirs there. They are very cheap and you can pay a little money for them. The people in my town are friendly. They can make friends with you. If you feel sick, there is a clinic (诊所)with a doctor and a nurse. I’m Andy. You can ask me for help when you have some trouble（困难，麻烦）. I think you will enjoy the holiday.
