I mean theoretically all inter-quadral relationships could be good for friendship, but in real life it doesn't really work that way. The odd thing is, my ILE boyfriend doesn't particularly like his mirrors, he feels they are too distant and self contained. Although mirrors are described as being a mostly work related IR and even then not very good at understanding. Activation would be easier in the sense of a friendship and ease of communication.

I don't really think I have had relations with someone in the same Quadra as me apart from my boyfriend, so I can't really say much about mirrors or activations or duals or identicals apart from my immediate impressions of them.
