Chameleon

Unobtrusive, unnoticed, does his bit without complaint.
Not entirely unappreciated, though possibly underrated is his part within the system.
Self-sufficient, yet in need of new scenes to attach to so as to allow growth and diversify ability.
Constant alterations, he's never home for long.
Becomes unknown, unrecognised.
Unwelcome.
Not the person he's been.
