My Parable of the Chores

A couple of months ago, one of my children asked me a tough question.
As I did my best to answer her concerns, I made up my own parable to try and help her understand.

My Parable of the Chores:

In order to clean the house, as loving parent, I assign out jobs to everyone. 
One child I ask to do the dishes,
one child I ask to vacuum,
one child I ask to fold the laundry. 
All the jobs need to be done.  - To those who might argue, one job or another is "more important" than the rest, imagine that job was left undone for a year in your home . . . . . they are ALL important.

Now imagine one child says:
          "Why don't I get to vacuum?"  
          "It's not fair that they get to vacuum and I don't."  
          "Aren't I good enough to vacuum?"  
          "Why don't I get to do that important job?" 

Loving parent answers this:
          It's not what I asked you to do.  I've asked you to do many chores. 
          As parent in charge of this home, I choose who I will ask to do what task.
          Me not asking you to vacuum does NOT mean:
                    "You aren't good enough to do it."
                    "I love the other child more."
          It just means, it's just not what I asked you to do. 

So now the children have a choice. 
Do they spend their time, do what they are asked to do, and do their best to do it well? 
Or do they complain, protest, and cry "Injustice!" Meanwhile neglecting the things they have been asked to do and leaving work undone.
