I always need some sort of pet around. They keep ya from being
  wrapped too much up in yourself or in the people around you.
  They just look at you and say, "feed me, pet me take care of my
  needs" and you're like, "damn, man - they just can't do it all
  without me". Keeps you humble because they do what they do and
  you serve them - they don't serve you. "
