Dear Wang Ying,
How are you? Summer holiday is coming soon. I'm going to the seaside for my holiday. But I don't like
to go there with my parents. I don't get on well with them because they are always trying to teach me. Do you
have the same problem? What about parents? How can we get on well with our parents?
Hope to hear from you soon.
Yours,
David Smith
