It's MY Tree

Can a squirrel ever get what a squirrel wants most? The squirrel loves a particular tree ("MY tree") and is happiest sitting in its shade eating pinecones ("MY pinecones"). But then the squirrel starts worrying. What if someone else wants to claim this tree, to call it THEIRs? So, the squirrel builds a massive wall around the tree. One that no one can get over. Perfect! Only, now the squirrel can't see what's beyond the wall. There may be a better tree out there, full of pinecones. Maybe even a whole forest of better trees... Believe every squirrel ever: the never-ending quest for MINE is sure to drive you nuts!
