I freak out if clothes are left on the floor.
I make the boys put their toys away IN THE CORRECT BINS.
I enforce the rule that one room must be picked up before moving onto the next.
And so on and so on.
But if my boys ever try, once they are adults, to come back and complain about my pickiness during their childhoods, I will pull out this picture and say, "Look what I let you do?!" And they will know they have lost the argument and walk away ashamed that they could have forgotten the awesomeness that was always allowed OUTSIDE.
(Everything in its place, people.)
