They don't really know the value of money, so they don't care enough to stop being wasteful pricks.Extra effort like.....
moving the Christmas wrapping paper that was in the living for 6 months?
The tent that was in the garden for 3 months
The BMX bikes they left outside all winter
The pool they left out filled with water for so long it went green
The halfpipe that wasn't protected and was ruined by the rain
The dog poo they only pick up once a week
The indoor plants that are half dead.
