My kids tend to pile crap up on surfaces.
'Specially Re-Pete. Here we have an odd assortment- ocarina, paper tablets, mini puppy, bits of paper, snack detritus, and my check stub at the very bottom of the pile.
Re-Pete is not picky about where she piles either... we have a small table in the bathroom, perfect for her schtuff...the hearth is perfect to line up her babies, under her Daddy's desk, even the stairs are utilized.
I wonder what type of label we could give her particular syndrome?
Heh, she'd make a great librarian the way she likes to line stuff up.
