INFP Here is why:
I-- not noisy, unobtrusive
N-- wrapped up in their own little world, not critical or picky about externals/details
F-- sensitive to the needs and desires of others, or at least capable of being so!
P-- flexible, adaptable, openminded
Seems obvious to me. How is this even a contest? Of course, it takes a good little INFP to be an easy-going person. The raw material may be in place, but they can misuse their potential when they turn evil, no doubt.
