Friend and guardian of the forests, friend of man's best friends, and part of the garrison to protect artifacts, this person lends a hand without fanfare. Experienced in the sacrifice of parenting, sustenance has become a masterful art from the earth to the table. Policing those who should be friends and teaching how to simplify home environments, there is an ever-growing expertise in research. When two dimensions are not enough, three dimensions open a new understanding. I am a volunteer's volunteer, like an artist who is an actor's actor.
Who am I?
