Belonging

This was quite a complicated matter. The little trash compacting machine had never had to wrestle with such a difficult machine. Where did this object belong, with the pronged sticks or the scooping sticks. He used every ounce of his memory to deduce its purpose and place.

On the one hand it was curved like the scoops, but then again to had prongs like the forked ones. Decisions, decisions. Wall-e places the spooned fork in-between the cups he used to hold the other plastic utensils.

How odd that something with a purpose can be so lost, alone amongst its own kind.

The next day Wall-e rolled thought the dust to fulfill his directive. As he passed his usual route he stopped to look for any more replacement parts in case of a tune up. As he grabbed a right optic from one the now deceased Wall-e units, he came odd realization. He and all the other Wall-e's have a purpose. To compact the materials into cubes and stack them. But yet he feels out of place from what should be his brothers and colleagues.

Nothing special about him. Two arms, box like body, treads and optics. As he thought nothing special. He has the same directive as all of them and yet he feels that he doesn't belong, stuck in the middle between these old models and something that he can't quite grasp.

He continued along with his BnL cooler to collect and compact. But these thoughts still somewhat lingered. Where did he belong. What made him so different from them. He then looked down into his hands an saw that he was carrying the odd looking green object. Was this the separation line He had no memory from when the others were working but he assumes that it is this trait that separates him from them but what did that make him. That question, of where he belonged, was it with them or with this unknown force.

Several days latter. Wall-e now knows where he belongs. It took nothing sort of trip across the galaxy and some new friends to find where he belonged. To be more precise with who. Eve, was with him. Not on either side but situated comfortably between in the middle of being a machine and something more. He was who he was and Eve was who she was.
It was together they belonged.

Sorry about the length but I hope it hits you as much as it does me. R&R
