This passage struck me as particularly amusing:
INFPs live primarily in a rich inner world of introverted Feeling. Being inward-turning, the natural attraction is away from world and toward essence and ideal. This introversion of dominant Feeling, receiving its data from extraverted intuition, must be the source of the quixotic nature of these usually gentle beings. Feeling is caught in the approach-avoidance bind between concern both for people and for All Creatures Great and Small, and a psycho-magnetic repulsion from the same.
Yes, I am a gentle being, quixotically aswim in my rich inner world of Feeling. And if I seem aloof or quiet, it's just that my feelings toward you are delicately balanced between concern and repulsion.
