My favorite flower is not graceful rose, gladiolus are not proud, but modest, tiny forest flower — cat's paw. I once saw him near the road when vacationing in the summer at the grandmother on a summer residence near Luga. I've been collecting in the sunlit hill of sweet scented strawberries. Suddenly stopped in surprise in front of me stretches a fluffy meadow. Tiny pink flowers resembled shaggy
the paws of a cat. The flower — grey fluffy ball, and in the middle like the pink droplet. Growing Bush, and therefore it seems fluffy. I gathered a small bouquet and brought it home. Grandma said that this flower is called cat's paw, people, everlasting, and in our village — bogacica. A bunch stood before my departure to the city — not wilted, the petals not showered. Sorry I was
to leave flowers, and I took them with me. They stood in a small vase all winter, reminding me of the summer. Since then, every year I quote from the countryside to the city a bunch of flowers.

Dear (имя),
     How are you? Hope you are well! I wrote you this letter to tell about my new house.
     Recently, we lodged in new house.There are 4 rooms like living room, children's room, bedroom and my own room. My bedroom is beautiful. Because,room is painted blue and as you know blue is my favorite color. In my room, there are big closet and soft bed, now I dont worry that my dress wont hold and I am not tormented by a sleep debt. Also, there is a good view from the window.When I wake up I see fine nature from window.In addition, in our kitchen,there are a lot of appliances.Thanks to them I can cook different tasty food.I love not only the new house, but also the neighbors.They are very friendly and kind.From the very first days of our arrival they help to adapt.
        Every things has disadvantages.For example, if earlier I walk to get to school, now I have to go by bus.Also,it's hard for me to find friends. But,compared to the old house this one is much better.Though usually I miss my old house.There are so much memoirs.
Best wishes, Lisa..
P.S Come to my new house.It will be cheerful
