With me, it didn't make me want to talk. I answered someone's question with something important, clearly felt like what I said warranted and needed a response, and they said absolutely nothing. I imagine that ends the conversation for virtually everyone. If it was supposed to inspire me to talk more, it wasn't working, so clearly not effective for me or that stage of our relationship. Maybe if they just wanted to see if I would clam up or get scared, that worked. I've spent years wondering if something was terribly wrong with me.
