Hi Masha! How are you? i haven't written to you in a long time , but now i want to share my idea . you know, i really like to read, but at the same time i rarely buy books , mostly i take them from the library , or read e-books . But recently, I went to visit my new friend , and you know, he has a separate room for the library , there are a lot of books, neatly displayed in a row , and it really inspired me to create my own home library . I wasn't really interested in it before , but I already bought shelves for books , my dad installed them in my room. I also bought a book, and i'm reading it now . In the future, I want to have a very large home library with a variety of books . Masha, do you have a lot of books at home ? How do you feel about the idea of collecting books? See you soon, Мasha!
