Person1: What's your little caper ? Come home so late ! We are all worried about you .
Person2:Oh , I am terribly sorry . But I was so captivated with the singer at the subway exit . So I forgot the time .
Person1: Singing ? At the subway exit ? Oh , it sounds like someone needs some money .
Person2:Oh , no , the guy was a musician who just sang . He played the guitar and sang so many cool pop songs . Many people were drawn to his music and there was no hat on the floor . He sang for appreciation , but not for money .
Person1: It is just pop song , you could have sung there too if you want it .
Person2:Oh , no , it was a kind of pop art . I like it but I couldn't do it that well .
Person1: Honey , just do it next time . Have you heard of the real art in the subway station in Russia ?
Person2:No , but tell me some . I am interested .
Person1: Many oil painting exhibitions are there . That is a kind of Museum Exhibition .
Person2:Are there many people there ? Do you think people actually like them ?
Person1: I am sure you will . There are some works , and some students who major in painting interpret the meaning for visitors . And people can enjoy the paintings while waiting for the train .
Person2:But I still prefer the pop music in the subway .
Person1: Both the pop music and the oil painting ate arts , but with different aesthetic values .
Person2:Dad , you talk well , but can you appreciate that kind of art ?
Person1: Not well enough , but I'm learning .
