Actually, my dad is an ISTJ, and though we share a lot of the same interests and we'd both prefer not to be in large parties/crowds, I still feel like we think VERY differently. I think he would like me to do things the ISTJ way a lot of the time, and this ruffles my feathers when things come up like how to get jobs and being responsible and such. I'm not irresponsible. I'm just slow, daydreamy, and lacking in real world confidence somewhat. I work hard and get all A's. I just tend to procrastinate and stay up late with stuff I could have done earlier. this is what my dad hates. One of my best friends is also an ISTJ, and we, too, share a lot of interests, but again, we think very differently. She's much more "by the book" than I am, but sometimes this is a good balance for an INTP, who may tend to take new ideas over the edge. She tends to think in black and white, and she has said herself that I have challenged her to think more in "grey" sometimes and not mark one thing as "good" or "bad." Sometimes, it's neither, or both. We've had a few little squabbles about this type of thing, but it's actually stimulating to talk these things out. My older sister is something like an ISXJ, but she has a lot of T. We enjoy nerdy shows and things together and generally get along pretty well, until I leave my mess lying around or say something about how I hate it when people try to make small talk.

She doesn't seem to understand why I hate small talk or other "superficial" forms of communication. She seems to think it's just rude of me. Maybe she's right in some cases, but really, not making small talk to someone when I see them doesn't mean I don't like them or that I'm being a snob. In fact, there are many people I like who I would rather not talk to. Sometimes it's just nice to be in their presence and remain in the background. So, yes. I love all those ISTJs, but our main differences or clashes tend to spring from my "failure" to meet certain standards (or what they see as "standard"s), especially socially and responsibly. Otherwise, they can be good, mature company, and even nerdy, too.

You may be surprised at how many nerdy, anime-geek ISTJs there are. Heh.
