Introduction
“Men and women can't be friends, because sex always gets in the way”, is the main theme of the movie “When Harry met Sally”. The script is a good example of the interpersonal communication ten stage model by Mark Knapp. This developmental model entails the stages of a relationship from it’s infancy to an ending.

During this stage people usually making “small talk” and it helps prepare the stage for future communication and interaction. In the movie, the second stage begins shortly after they begin their long trip when Harry asks Sally “why don’t you tell me the story of your life?” There is lot’s of small talk and dialog; talking about happiness and who is more prepared to face death, to analyzing and interrelating to the characters of the movie Casablanca.
