Hello, is this Ava? It's David. You know what? My favorite singer, Sam Smith, is coming to Korea next week. Can you believe that? He is having a concert next Saturday at Olympic Park Stadium in Seoul. I was wondering if you want to come with me. He is a pretty, famous singer in the world as well as awesome. As you know, he is a guy. However, he has an amazing voice. Also, his songs are pretty good. I like to listen to his song called "Let me down". The tickets are a litte bit expensive but they will worth the money. If you go with me, I will put the bill and I will pick you up in front of your house. The concert will definitely be great. I expect to go to the concert with you. I really don't want to miss the concert. It's a once-in-a-lifetime opportunity. Please don't make me go there alone. Will you come?
