Hi! I have something to tell you about. I went to a library with my friends yesterday. I wanted to study at home, but my friends suggested studying at a quiet place. So, we went to the library near the station. It was very beautiful, and there was a surprise. There was a café in the library. Do you think such cafés will become popular in the future? Your friend, Alex
