New Skills or a hoarder in the making?

Adella has thing thing... She likes to carry around lots of stuff.  She needs to have things in both hands -sometimes multiple things.  

I came down the hall one day to find this -

Little miss smarty pants had figured out she could carry more stuff if she put her stuff into a bigger vessel (this was only a lid, so not really that big).  But you tell me, is she just getting smarter, or do we have a potential hoarder on our hands?
