Been doing a lot more thinking on my Dad's type, and in addition to that, my sister's. I can't figure her out for the life of me. So I thought, if you don't mind, I'd recruit some help.
Here's what I do know:
She took the test I initially took (gag test?) on that site that's in my signature. She tested as ENFJ, read the profile, and it didn't match --- according to her. She also told me, somewhat vehemently, that "you can't type me because I'm not a stereotype like you. You're weird."
From observation, I vote ambiverted. At work and at church, she is extremely extroverted --- nonstop communication with her friends, with her customers, with her coworkers, etc. She's very friendly, very nice, and somehow able to "understand people". I don't really know where she gets that from. T/F difference perhaps?
In stark contrast, at home, she acts like a total introvert. Does nothing but read books, watch her TV shows, and play with the puppy. Gets on the computer every now and then, but mostly just for MySpace and stuff like that. Oh, and more reading.
I'm not sure if she prefers Sensing or iNtuition. We were both homeschooled, but I excelled in everything but the dreaded N math --- Algebra. I'm generally self motivated, but she requires.....more pushing from Mom. She isn't stupid --- don't take it that way --- but she tends to excel only in what she "likes".
We tend to get in arguments a lot (we have a good brother/sister relationship though, we're not....at each other's throats or anything) but I have difficulty telling if these spats are T/F related or I/E. Or even S/N, if she's an N.
Sometimes I just need some alone time, to be in introvert land, but she insists on going over to so-and-so's and wants me to go too since we were both invited. I explain that because "everyone" (the whole church, or youth group, or work group, or whatever) was invited, then they're not going to miss me. She usually gets upset at this point and stomps off to God knows where.
In other cases, it'll be something more like......description. I'll try to ask her something, without any kind of negativity or sarcasm, with an honest intention to learn, and she blows it off. I'll try to probe a bit, to see why she does what she does, to learn about it, and she either gets irritated or....can't explain it. I don't get that --- I'm able to explain almost every move I make. Why can't she?
In terms of J/P, I think she's middle of the road here too. Sorta. She says she has OCD like Mom and myself, but I know from living with her that she doesn't have it anywhere near as much as us. For example --- she's OK with leaving the cups on the coffee table when she's done drinking her pop or whatever, and she's cool with leaving her gross socks on the floor when she gets home from work. She's also OK with leaving something out "because she'll use it later". Oddly enough, though, her bookshelf is in perfect order (just as orderly as mine) and so is her DVD rack. But the rest of her room looks like a tornado went through it.
I once made a joke, saying I'd write another book, and title it "How to Plan a Spontaneous Evening". Mom thought it was funny. But that's here nor there. I think my sister does a little bit of both. She does plan things....sometimes. But other times, she just randomly gets up and says, "I'm gonna go to the mall". I'm having issues here deciding if she's J or P.
She also gets along with my friend Jordan very well, albeit in a different manner than I do. He's an ISFP.
I don't want to make this post forever long, so I'll stop here. Any suggestions out there? Comments, concerns, questions welcome.
