User: I wanna watch a movie that makes me feel sad at the end.
Assistant: I found 100 movies that might fit your needs. How would you like to narrow them down?
User: Just filter out the movies that make me want to cry. I don't wanna cry. I just wanna feel a slight sense of melancholy and a hint of bitter-sweetness.
Assistant: Okay, I have found what you're looking for. Thirty movies fit your needs. Would you like to further narrow them down?
User: Hmm ... what do you think my closest trusted friends might like?
Assistant: After looking at your contacts, I found that most of your close friends prefer to watch movies that take place in Europe. Would you like me to narrow your choices down based on that filter?
User: Yes, please.
Assistant: Okay, I have narrowed your choices down. You have 10 movies to choose from. Which would you like to watch?
