I can masquerade as an ISFP or ESFJ, given that I was raised to act like one. This drains the fkn bone marrow out of me though.
Naturally though? INTJ. If I'm not careful, it becomes my norm. I deal with people a lot, so I don't let that happen. I love Ni, but I need reality. I love Te, but I also enjoy keeping friends. ;-P
