Preliminary task

Hello !!
Today we decided to start our preliminary task , so I have to do my own research and give my own ideas.
My idea is to use a simple girl having a conversation with some other person , i was thinking that is better to use a other girl this time , because the idea of a girl and a boy is always the same.
I was thinking to put a conversation between 2 friends. The use of sound for me is always very important to give the advance idea to the audience of what is the movie about or what is going to happen. The conversation should take place in a restaurant or some public place.
