Okay, I the "hmm, okay" part.
One is when I ask my dad for advice. He gives me advice, and then gives me advice on top of that that I didn't really ask for. At some point in the advice-giving session, I decided that I got what I had needed, and I had already "checked out" of the conversation mentally before he was done because he sort of surpassed my question. So the hmmm, okay was for the extra stuff, even though I listened to the rest and got a lot out of it.
My advice, if this is happening, is to give a little bit of advice, and if an ENFP is interested, he or she will 100% ask you another question or urge you to go on, pretty much guaranteed.
