There is kind of an extreme situation in my family. As my dad is LSI, mom EIE, sister ESE and brother LII, everyone (expect me) has a dual, a semi-dual and a kindred relation in the family. I'm EII, so my relationship types with them are superego, extinguishment, mirage and business. There is a clear confrontation between me and the rest of the family, I don't really get along in long term with any of them and they're all really close with each other.
What comes to other relationships, I won't seek for alphas or betas, but being brought up by them has probably affected my behavior and made me more tolerat to people from those quadras. I have lots of friends from alpha/beta. E.g. my best friend is an IEI, a beta and my quasi-identical, but we really get along very well despite the misunderstandings. I wish I could get to know more deltas in the future to see if this upbringing has had some sort of fatal impact on my "deltaness". The problem is that I don't really recognise deltas/don't know how to approach them, it's like I'm somewhat drawn to alphas/betas.
