I have been living with an INFP for the last 5 years, known some INFPs and getting along with them, I can say INFPs are the definition of pure. They're affectionate and caring, they're cautious, empathetic, also vulnerable and selfless people. Their idealism is something you can't complaint about, they're just born to be that way. I love how INFPs are sensitive to their surroundings, they're softhearded who can't see bad things because they hate it.
