-Dear Richard
-Thanks for your letter. It was great to hear from you again. I’m sorry I haven’t answered earlier but I was really busy with my school. 
You asked me to tell you about how I went to the amusement park. Well, it's very interesting. I and my best friernd Mark went there with my parents. In the park a lot of different attractions. When we arrived our eyes fled from what we saw. I wanted to ride all the attractions at once. But unfortunately there were huge queues. Therefore, we dispersed all the different attractions take turns. When someone's turn came, we called up. How good that now is the age of technology. After all we decided to refresh ourselves. On the way to the house, we stopped at a cafe and ate. It was the best day. I hope that soon we will go there again.
By the way, When will you be able to come to us? Have you ever been to such a park?  Do you like parks with attractions? Can we visit this park together?
-Sorry, I have to go now because my Mum asked me to help her with the washing up. Drop me a letter when you can. 
-With best wishes,
-ИМЯ своё.
