Before that the idea is just so foreign to them that they have a difficult time grasping what is going on.  I would often get the question, “but where do I put the code”.  The answer is everywhere.  Thinking in terms of objects and programming their behavior makes sense.  People get that.  Make a Robot and teach it how to walk.  If I tell the robot to walk she does.  Ok great.  Now I have all these objects that do stuff where do I put the code?  This is where people stumble.  In my opinion the leap to understanding is very short.  The answer is simple.  (Answer: It depends on how you want to interact with the user).
