Chores

My kids have chores they do each Saturday.  This is not a surprise to them.  They know they have them.  They can pretty much even figure out what chores they have on their own.  There are three sets of chores for my oldest three kids.  And they rotate through them week by week.  Each of the older kids have four chores, plus cleaning their room (Josh Jr. has and extra, which is cleaning his birds' cage).  The chores are not hard.  It is one bathroom for each kid and two rooms to vacuum and a hall or the stairs.  They can get all of their chores done in under an hour (they have done it before), but usually it takes ALL DAY LONG!!!  Like today.  We talked about chores this morning at 9:15.  They all knew what their chores were.  I even offered a prize for the first of the older kids to get their chores done as incentive for a fast chore day...  Sadly it was not to be.  No one had their chores done by lunch, like I had hoped.  In fact no one had them done by 3pm either...  And my slow poke of the day was still finishing her last chore as I was putting dinner on the table...  My question is... Why if you can get your chores done in an hour, would you choose to take 9 hours???  ( hour of being told by mom to go do your chores can not be THAT much fun, trust me it wasn't for me.
