My mind was blank i was very tired with the process. When he said movies , i grabbed the opportunity and told him about a recent kannada movie called 'UPPI2' which had released on that on that day. He told me to tell something else , so I started talking about another telugu movie called 'Baahubali'. Then he started laughing and said "oK, enough of movies, tell me something else."
