Priorities
For the entire day, M-O had been following WALL-E around for the good of the Axiom. Foreign contaminants were taught to him as being dangerous to the passengers. It made his job important, and he liked his job. A lot.
And he'd finally caught up to the filthy bot, but instead of pulling out all the stops that 100% contamination deserved, he found himself defying his program to be as fast as possible and using his softest brush. Without even realizing it, his priorities had taken a slight tun.
What was that word? It wasn't used anymore, but it still seemed to apply perfectly...Oh! Right! "Friend"!
Friend. n. A person one knows, likes, and trusts.
Huh. He'd never had one of those before. How cool was this?
