Base and Suggestive/Dual-Seeking Interaction
What you most need and desire in support of your Base, but struggle to provide for yourself, is something your Dual is perfectly equipped to provide for you. Indeed, he will be eager to share his most natural and valued strength with you, and you will probably need provide only the most subtle hints in order to get what you need psychologically.
Often, your Dual-Seeking function is something you might not even be aware that you need. Like the phrase "ignorance is bliss" suggests, if you have rarely been exposed to or made aware of your needs in the area of your Suggestive function, you may even go on for many years not even realizing what you're missing. For a person exposed to Duality (or Semi-Duality) for this first time, it can be very much like a sugar-deprived child tasting candy for the first time: you're likely to think "where have you been all my life?" and may even become "addicted" in a way. What you once existed happily without, all of a sudden you can't bear to let it go, and you find yourself wanting more more more.
Creative and Mobilizing/Hidden Agenda Interaction
Even though the Mobilizing function is considered weak, you feel a certain phschological pull or urge to improve yourself and become strong in this area. Consequently, you naturally-- albeit sporadically-- put a good deal of time and effort into your Hidden Agenda. When this happens, however, efforts related to your Creative function tend to get put on hold, or neglected.
Even though your Creative function is strong and valued, you may find yourself sometimes wishing for it to just take care of itself, as you focus on your Base and Hidden Agenda. As a result, the Creative function may be referred to as a "pseudo-dual-seeking" function. Next to your Dual's Base function, his Mobilizing function will probably be the second-most useful to you, as yours will be to him.
The Creative-Mobilizing interaction between Duals is probably what really keeps Duality so fulfilling and interesting, as you naturally encourage and support each other in self-improvement efforts related to your Hidden Agendas.
Role and Ignoring/Observing Interaction
At times, you will feel the need to exert yourself in your Role function. Efforts related to the Role, however, are uncomfortable at best, and something that you will try to avoid or put off as your Role function directly opposes your Base.
Expending too much time and effort in your Role can leave you feeling particularly exhausted and out of touch with yourself. However, as stated above, you will still feel pressure to focus on your Role at times, as a "necessary evil," particularly when it comes to defending or protecting yourself against pressures on your Vulnerable function, which is even more uncomfortable to focus on than your Role.
Your Dual is perfectly suited to you, then, as your Role function is his Ignoring-- or Observing-- function. Your Dual is one of those rare individuals who will likely never put pressure on your Role; and when other forces try to do so, your Dual will be there to support you and help navigate you though, while at the same time helping you to not take it all too seriously.
Keep in mind that your Dual is not very likely to want to actually take over for you when it comes to your Role function, so you will end up having to take care of yourself much of the time. You Dual will be there to help you, but more as a sort of coach/cheerleader. You will still be the one out there on the field, playing the game.
Vulnerable/PoLR and Demonstrative Interaction
Just as your Dual's Base supports your weakest valued function (Suggestive), your Dual's Demostrative function is perfectly positioned to support your psyche's weakest unvalued function, your Vulnerable function, or Point of Least Resistance.
Because the Demonstrative funciton comes so naturally, while at the same time being unvalued, one is often consciously unaware of its manifestations in himself, and hardly cares to think about it even when it is pointed out to him. Your Dual's Demonstrative function, then, is perfectly suited to your PoLR, which is so weak and unnatural to you, that you don't want to think about it, either.
So, you and your Dual can both exist together, he performing without much thought his Demostrative nature, in a way that you will be free to almost completely neglect the Vulnerable in yourself, and avoid the necessity of engaging in it as long as your Dual is around.
