I do find SP's typically don't care much to talk about or share their depth of character like NF's or NT's would. And living in the moment usually means SP's are as deep as the moment allows them to be, instead of drawing on the past and particularly future plans. It's there but it doesn't show in communication quite so much.

"I feel there are two people inside me - me and my intuition. If I go against her, she'll screw me every time, and if I follow her, we get along quite nicely." -Kim Basinger
