Snippets of conversations--what is the backstory?

As I walked by I stopped for a second to listen. The group was talking about the movie Avatar and the teacher said to the class, "the only purpose of life is to love, build relationships and care about others. There is no other reason for life."  

None of  the students disagreed, I thought interesting that the teacher chose this movie to lead a discussion on the meaning of life. I would have chosen, Monty Python's The Meaning of Life as a better starting off point for that discussion. However, I would not have shown it to my high school students, but to my University students. Not only is the movie funny, but it is totally irreverent and that in itself is a reason to celebrate life.

There, of course, is more than one reason for living and I suspect the teacher was trying to make a point to get some discussion from the students. I hope she did because before I heard any responses, I had to move on.

I  notice that as I wander around and through life that I often hear snippets of conversation, I am sure we all do, and I find it fun to imagine a back story to the conversation. I wonder how many others do this? 

By imaging a back story the conversations are put into focus for me. I don't do it all the time nor do I make any judgements about the people I hear talking. I use the backstory to help build stories that I might write one day. I also find this exercise fun. Using my imagination to create the back story or using my imagination to continue the conversation to a conclusion, is an enjoyable pastime and goes along well with people watching.
