There is a faint sadness. My best friend is rich. I am poor, and I am the kind of party that goes to work every day. She didn't. She has her own shop. Therefore, she often asks me to sing, dance and travel. I'm not available. She never goes out for a walk. Everything she likes looks more expensive. If I help her a little. Will treat me to something very expensive and delicious. The biggest worry is that I always feel that she and I are not from the same world.
