When you are ISTJ and they are ISFJ
Same principles, kept at different temperatures
The ISFJ Defender shares your dominant Si, so you both treasure the familiar and keep your promises in similar ways. The difference is in the second function: you use Te to ask what's right and efficient, while they use Fe to ask who might be uncomfortable. On the same task you'll organize the system and they'll look after the people, and that can make you a remarkably solid pair. Because ISFJs tend to swallow their hurt, it helps if you're the one who asks first.

In love
