Dear Jenny,

How are you? I am visiting my cousin Howard in Australia. It is hot in Hong Kong but it is cold in Australia in June. When it is summer in Hong Kong, it is winter in Australia. It is snowing heavily now. I like snow a lot and it is a white world outside. I will play with my cousin in the snow this afternoon. We want to make a snowman. I think it is very interesting!

I like my cousin's house. It is big and there is a beautiful garden（花园）. We can play ball games. My cousin's neighbors are friendly but they cannot speak Chinese. I talk with them in English.

See you next month.

Tony
