 "A Fly in the Room"
 
A:    That fly has been buzzing around the room for an  hour.  I have been trying to study.....it is so annoying. 
 B:    Get  up and open the window.  It  will go out.
 A:    Where  have you been this past  hour, by the way?  I thought you wanted to study with  me.
 B:    I've been learning in the other room.  It is much  nicer to study in front of the tv.  I have been watching the news at the same  time. 
A:   You  can't study and watch tv at  the same time - that's why you've been failing  the tests  lately.
B:   I haven't been failing.  It's true I haven't been doing well - but I have not been failing!  That's not fair! 
A:   Oh  there's that stupid fly  again.
B:   (Opens the window and the fly goes out)   See, you've been wasting your time trying to catch the fly.  It  has been trying to get out the window all this time.
 A:    Yes, and I have been too busy -  and too lazy to get up.  Anyway, come and join me  here, we can study  together.
 B:   Alright.
