I'm pretty sure that my mom is an ISTJ, and we rarely get along, but it's pretty great when we do.
-We're at our best while bonding over generally enjoyable activities like shopping, watching movies, looking at funny pics, eating at a restaurant, etc. There is such a wide age gap between us that we can't really relate through Si, so it's easier for us to get along while using Se.
-We are at our worst while discussing sensitive topics like politics, religion, culture, etc. I think it's mostly a Fe/Ti vs. Te/Fi thing: I usually like to consider all sides of an issue and why people might feel a certain way, and she tends to state her opinions like they're fact.
My dad is an INTP, and we almost always get along.
-We're at our best while discussing things like politics. Although we disagree about 40-50% of the time, we're always civil and can discuss/debate without getting personal (although we tend to avoid the topic of religion). We used to play video games on a regular basis, and we always got along during those times. When he was in a men's church group, he often had "challenges" (for example, planking in a public area) that I would help with. Those were also good times.
-We're at our worst when more personal/emotional stuff comes up. He gets really quiet when my mom and I fight, and if I try to get him to see where I'm coming from afterward, he reacts with apathy and/or anger (ie. "I don't care!"). As a feeler, as well as a Fe/Ti user with a good understanding of fairness/logic, I find this hurtful. I feel like he knows I'm in the right, but doesn't want to admit it.
The way that they interact is sort of... well, I'm honestly surprised they're still together. My dad tries to cook while working from home but is forgetful and ends up burning something, my mom gets home from work and is mad, they fight, one of them involves me, and it's just a disaster for everyone. Plus I've only seen them kiss, like, once or twice o.o
