So much dirt, so little time

Legend is playing outside in the back yard. He abruptly runs over to his sand box and exclaims, "Dirty!"

He then puts considerable effort into ridding the box of its offending dirty sand, yelling "Dirty" all the while.

Up until now I thought he loved all things covered in dirt... maybe he was trying to spread the dirty rather than get rid of it.

He does keep me guessing.
