Why does he think this?

My second musing of the day.  I wonder why some people think that taking care of a house and two tween boys is not exercise?  Not only did I do two loads of laundry today  and clean up doggy poo.  But I also mowed and weed wacked said pen and then some.  After that I transplanted a tree.  When he gets home tonight asked if I was going to play basketball with them.  When given the answer No, what does the fool say.  Oh yeah he says but it is some exercise.  I would like to see him do as much work as I do in a day.  I could run circles around him.  Oldest boy so lazy will not even take out the trash.  What is a Mom to do......
