yeah my sli bf can be very outgoing, but it's an effort. I can tell that he's in "outgoing mode." Either that, or when he's drunk he seems outgoing. He comes across as gregarious and smiles a lot. I was confused at first because in his photos he didn't have the ISTp "eyes" but then he said he was drunk in most of his photos. Around me he is way quieter and zones out more. But w/ others he tries to smile a lot, asks more questions, etc.
