Написати лист моєму другу на тему моє хобі на англійській мові будь ласка

Dear Hailey,
Thanks a lot. I was happy to get your letter. I was surprised that you can ride a horse.

In your letter you asked me about my favorite activity. I like to play the guitar. Of course it 's my hobby. I began to play this musical instrument when I was ten. And now I play very difficult musical compositions.
What's more, I've taken part in several contests. I 'm sure that it's rather difficult to play the guitar because you must practice a lot to be successful.
As for my dream, I 'd like to become a famous guitarist.

I'm sorry I must go to musical school. Write back soon!
Best wishes,
Joshua
