The Arch-Fiend
I see decay.
I have two ISTP brothers and one INTJ brother. We all get along really well and are the only people that really understand each other. I also have many other siblings but none with great relationships like this. There is something about INTPs, ISTPs, and INTJs that is similar and connects them all. What do think these types share that no other types do? What do they have in common and why do these relationships work so well?
