  Dear Mai,

I’m very pleased that we’re going to be pen pals. I’ll tell you a little about myself, and you can do the same when you write to me.

I live in an area of London called Maida Vale. It’s quite near the centre, but there are parks nearby where I often take my dog, Mickey, for a walk. I live with my parents and my younger brother, Paul. My father works for the post office and my mother has a part-time job as a nurse.

I go to the local comprehensive school, where I have a lot of friends. I like most subjects, but not all of them! In the evening I sometimes visit friends or stay at home and listen to music, and at the weekends I like going swimming or horse-riding.

At the moment I’m working very hard because I have exams soon, so I’m spending a lot of time in the library.

  I’m looking forward to hearing from you. Write soon!

  Best wishes,

  Mary
