If i have done something you appreciate .. SHOW IT!!!.. reaffirm it ... OR do something in return you know I appreciate .. The worst thing for me.. is to feel undervalued.. or that effort I put in is just taken for granted..
And stop looking at our face for emotion.. listen instead to our voice.. if it goes deep but soft.. If I have trouble suddenly meeting your gaze.. If I suddenly seem very interested in that little dust bunny in the corner.. I am in a right emotional place.. And would be putty in your hands if you saw and understood that..
Emotion comes very easy and very deep for INTJs.. But expressing it requires effort..and that is the full circle.. appreciate the effort.. and more emotion will come
