I was talking to my cousin one day (who I believe to be INTJ) and I brought up the topic of dreams and possible theories related to them. Instead of responding with his own opinion (like most of my nf friends do), he simply gave me this blank stare which I found to be highly offensive. My ESFP dad relieved the awkward silence with a more down-to-earth topic and he went right back to normal. He is a witty, jobless, computer expert who seems to have no opinion on anything at all (he can't even tell me what music he enjoys). Why the heck did this happen and how can I avoid it next time?
