Dear Laura,

Hi! I am Veronica, your new pen friend from Singapore. I got your name and address from the Making Pen Pals' Column in Buddies magazine and thought I'd write to you. Well, let me start by telling you something about myself. I am 13 years old and I am studying in secondary one at Westdove School. I have just finished my exams. I live with my parents and younger sister in a five room apartment. I like swimming, playing tennis and reading novels. I love the outdoors, especially the sea and I have been on several trekking (long and hard) tours abroad. I enjoy listening to both pop and classical music. My favorite food is pizza and I love making it myself because I like to make it with lots of cheese and pepper. To sum it up, I am a talkative, caring and patient person.

I guess life in London must be wonderful with all the interesting places and good food to enjoy. I'd love to see the famous Big Ben. I hope to visit London during one of my school holidays. Laura, I would really like to learn more about your culture and lifestyle. I hope you will write back. I have enclosed(附有) my address and telephone number. Please feel free to call me if you make a trip to Singapore. I think you should because it is a wonderful place to shop. Till then, good-bye!

Yours faithfully

Veronica 
