Um, what? One of my friends is an ISTJ and she's one of the quirkiest friends I've come across. Or did my dazzling INTPness coax her out of her obsessively-structured shell? xD Seriously, though. Once you got to know her you wouldn't assume for a second she was an ISTJ. I was almost horrified when that was her result.ISTJ's: What a boring personality type!
Worst type for me? ESTP. My mum. She compares me too much to the "average teenager." "Normal teenagers go out with their friends", "Normal teenagers want to get a job," "normal teenagers get down and study." No. No they don't. Is my mum mis-typed, or do all ESTPs have a knack for comparing things to the 'norm'?
Oh, and another thing. Her indecisiveness when clothes shopping. Her absent-minded, lack of awareness of time tendencies despite living and dying in her watch. The "You can't assume something is going to happen if it hasn't happened before!" motto, her annoying alternating from F to T.
As for ENFPs, yar, I have a soft spot for them too. :x Despite the fact 'He' can't desist from distracting me constantly during Biology, which I'm failing as it is. *sigh* Only an ENFP could get away with distracting me from my work.
