Really? Weird! The biggest mooches I've known have been NFP's, consistently throughout my life.
After reading your comment, I wondered if my ESTP guy is more independent because of the way his parents raised him, but I realized that my other good ESTP friend comes from a family of irresponsible people and hasn't really had anyone from whom she could learn. She's very generous with her money and takes full responsibility for herself. Strange. I wonder what the experiences of others have been with regards to ESTP's and mooching.
