Dear friend,

Thanks a lot for your letter - I was really glad to hear from you. Sorry, I couldn't anwser earlier - I had too much homework to do.

That's cool that you've been on a rock-n-roll concert - I remember how much you wanted to get there! Anyway, I'm not a fan of rock-music, it's to rude for me. I prefer pop music which you can usually hear from every radio. I don't really like going on concerts. I would rather walk with my friends. I've been on 2 concerts, but I didn't like them - so I don't go there anymore.

I need to help my mom, so that's why I must finish my letter.

I'm looking forward to hear from you soon.

Best wishes,

  Dear friend,
  I have just arrived on a new planet and want to talk some about my empression. Firstly, you need to know that this planet is very beautiful and it is very different from the Earth. It has green water instead of blue, and grass is red. My journey goes very good, it's a lot of interesting things here. I'm going to return home in a month. Also, there are very kind and smart people on this planet. They told me some cool facts about their home and even talked to me about some secrets of this place. Well, at the moment i feel peaceful. This journey gives me as much of good emotions as i can't write you about how i am happy. But on the other hand, i miss my home - the Earth.
  Sorry, i cant write more, i need to help my new friends. How to hear from you soon.
  All the best,
