I very much agree with the phenomenon misutii talks about. It's the classical dual phenomenon of initually undervaluing one's dual. As a similar example there's a nurse in the place I work, she's exact dual to me. I end up being very distant of her, because we never ever have anything to talk about. We have very warm, but very distant relations, since I support everything she does and vice versa, but we can't handle similar information at all, so there's no area of contact. This has led some socionists into claiming that actually illusionary or semi-dual types are better than duals. In my opinion it's a matter of preference and adaptation. Each relationship has its own kind of dynamics, strengths and weaknesses.
