Reason #216 I don't talk to my coworkers

Except for a select few, I pretty much keep to myself while at work.  Other than a smile and simple 'Hello' in passing I do not typically reach out to people for conversation.  My friends tell me I should give people a chance and try initiating conversation.  One day, while in the cafeteria, a woman I've seen a few times sat next to me.  She was reading an article in a magazine about the movie Snakes On a Plane starring Samuel L. Jackson.  Recalling my friends suggestion, I thought I'd give it a shot - (this is the conversation that followed)

Me:  Have you seen that movie?
Coworker:  What movie?
Me:  Snakes On A Plane.
Coworker:  No, I don't think I've ever even heard of it.  What is it about?
Me:  You mean aside from the obvious? Snakes on a plane.
Coworker:  No, I said I didn't see it. What is it about?
Me:  Umm, snakes on a plane.  You will probably get just as much information from the article you are reading and not have to sit through the movie. 
Coworker:  What article?
Me:  (pause) The one right there in front of you - that you are reading.
Coworker:  Is that what this is about?  I wondered what this was.
Me:  (sigh) Well, my break is over.  Good luck.

I should have known better.  I made a mental note to think twice before following some of the advice I get from my friends.  As I walked away I wondered how many of my brain cells just commit suicide.
