Dunno. You will have to ask a non.

I went outside today and had some interactions. I dont know if other narcs specifically do this. I'm not aware of anything on my part. But from my dealings with others just tonight, despite intentions on my part, the other party always seems to have expectations. Not just of what they may want me to be to them, but also expectations of what they can get from me, what experiences they will have with me, etc. Its like ideas in their head but its more complex than mine. In fact, most of the time, for me, its just talking or whatever. Simple.
For this, I like having a more black and white approach. Makes things simple on my part. (supply or not) but it makes me feel awkward when the other party is not the same.
