Dear Liz，

My stay in Thailand has certainly been the experience of my life．

Life is busy and exciting．Bangkok is just like any other big city with a population of 10 million and heavy traffic．I'm very lucky because my host family is in a nice quiet area outside the city．There are Mr. and Mrs. Phairat, their son Sanan, who is 18, the daughter Chinda, who is 16, and Grandpa and Grandma．

I go to an international school with Sanan and Chinda．The school teaches about 70 percent in English，and 30 percent in Thai. I've learned some spoken language，but Thai writing is very difficult．The cooking lesson is my favourite．I'm learning all about Thai food and culture People don’t use chopsticks here，but spoons and forks．When I come back，I'm going to cook you a real Thai meal．

Last weekend we visited some temples．We also drove to Pattaya beach near Bangkok．I thought it was great，but Sanan and Chinda say that next month they’re taking me to Phuket Island，where the beaches are even more beautiful．The month after next，we’re going to travel to Mr．Phairat，s hometown in the north of Thailand．The Phairats own land there，and they have two elephants．I’m going to ride those elephants — and even wash them．Sanan and Chinda say it’s really fun．

I'm amazed by everything in this country，especially by the elephants．Elephants are an important pan of Thai culture and way of life．They have been a traditional symbol(象征)of Thailand for many years in times of war and peace．In the seventh century，a Thai king trained 20，000 elephants for battle．

I’ll tell you all about my Thai boxing(拳击)lessons next time I write．

Love,

Mandy
