Nesting

A few years ago we built our son a loft.   It was a delusional attempt to help him keep his room clean by giving him more floor and shelf space.  Even though that particular experiment was an abysmal failure, it did allow us to study the aerial nesting habits of the American Tween.  Yes, I said "nesting".  I have long held a hypothesis that there are many similarities between children and critters.  Anyone who has had a dog and a toddler at the same time can't help but notice the similarities!  When left to his own devices, my son 'feathers his nest'.   He fills up the space next to the wall with books, electronics, laundry (the state of which is heretofore unknown), and empty (I hope) cups.  To the untrained eye, it could be interpreted that he "keeps crap in his loft".  To the parent-naturalist this is a gold mine!
