Dear Max, 9th January
How are you? I’m fine. I’m in London at the Apple International School. I’m in class 2 with seven other students. The students                       in my class are very nice and interesting people. They are from different countries. Nicole is French. She is from Paris, France. Tom is Dutch. He is from Amsterdam, Holland. Mr. Den is Chinese. He is from Beijing, China. Mr. and Mrs. Soto are Japanese. They’re from Osaka, Japan. Paola is Italian. She is from Rome, Italy. Misha is Russian. He is from Moscow, Russia. Our teacher is Gregory Maxwell. He’s young and he’s a very good teacher.
