16. HW1 1. Model a conversation. Write down a real(istic) conversation between two people (can be borrowed from your life as long as it is legal). For example, consider the exchange with the barista when you are buying your first cup of coffee early in the morning. For each utterance, write down all the internal thoughts, processes, assumptions made and calculations going on inside the speaker's head before it is spoken aloud. Based on the above how can we make chatbots more real?

17. HW1 2. What is the ratio of "internal thoughts triggered" per "external utterance" in a typical conversation? While reading a book? Watching TV? How much does it vary based on the topic of the conversation, book, or show? Defend your answer by examples.

18. HW1 You read about “common sense”. How many common sense facts do you know? Defend your estimate.
