Hello ! How nice it was to receive from you new letter — I read it a few times in a row. You actually gave collie Puppy? That's great! What did you call it? How do you treat it? Unfortunately, my parents strongly disagree keep in the house a cat or dog because they are afraid of wool, damaged furniture and Wallpaper. And I think that the animal must be — after all, how much joy, warmth and love brings it all home! I want to tell you that I started attending a circle macrame at our club. It turns out that weaving dates back to ancient seafaring craft — knitting knots. The rope can be painted in different color and weave of her toys, ornaments, planters, handbags and even clothing. I already figured out what gifts will make all for the New year. Latest news: in our class there is a new girl with an old Russian name Arina — gymnast from circus. She has an amazing braid to his knees. It is surprisingly sociable, she made friends immediately, as if were together for eight years, and not only a week. At its invitation, we whole class went to the circus. Arina were amazing, I got the impression that it may meet in any figure, so it is flexible. It is a pity that after a few months it will go to a new town on tour, the circus is not in place. And in my school soon will be traditional ballroom dancing competition, and now almost my entire class disappears during rehearsals. Many of our girls from the first class go to the dance, so the waltz, and Samba we set ourselves. At first she was afraid not to find the right partners, because Samba is very catchy and energetic dance, but our boys did not disappoint us. So have all the chances to win! Anya imagine, I only recently learned that in our house lives a very interesting woman — Anna Kovtun, a war veteran and known throughout the region craftswoman: she embroiders pictures. How amazing it turns out! When you look from afar, it seems that before you a piece of wildlife. Anna Ivanovna has repeatedly taken the first prizes at various exhibitions, and once even ran an article in the newspaper. My mother promised that in the summer again would get me a ticket to "Aistenok", and I go to camp. Finally we meet again! I have missed you so much! We are definitely going to swim in the lake, dance and sing songs under a guitar. And in the evenings to come up with a mysterious history. I even think that they are worth recording — if you ever release a book? What all can be (I know, you laugh now!). I wonder will we recognize each other in a year? Is there a big change? I look forward to your letter. Write, what is new in your life, what are your plans for the future. If possible, send me a photo of you and the puppy. Because probably already done a lot of interesting shots. On this finish. Prior to the meeting. Your friend.

The town i live in is not very large and there are no big galleries and museums in it. but we have a good natural history museum in our town. last week i was on an excursion there. first we listened to a lecture on the history of our region which was very interesting. then a guide showed us the exposition of the museum. we walked through its halls looking at different stands with exhibits. there were ancient vases and coins, dishes and bowls, tools and arms. the guide told us about the origin and the age of the exhibits and answered our questions. the girls asked questions about national costumes and dishes and the boys were interested in arms. the next hall was even more interesting. there we saw stuffed animals and birds. it was a small zoo of the region nature. there was also an aquarium full of different fish, tortoises and shells. the collection of minerals was interesting, too. i have learned very much from my visit to the museum.
