I mean like they just literally pop out of nowhere and start talking to you and BAM. They're so good at dealing with people, at least the ones I've met. I was working as a F2F worker once and this other F2F worker, who I strongly believe to be ENFP for instance, just came out of nowhere peripheria and told me his whole life story. All the ENFPs I've met have always just sort of popped out of nowhere, from not knowing at all who they are to total disclosing and connecting. And they notice you before you notice them. So yeah, maybe a bit like ninjas.
But ENTPs for instance, it's a bit different ime. They do their thing and if you're around and show a small sign of liking what they're doing, then they will make themselves more available to you, or if they like you from the start, they will still just make themselves more available, but not in the ENFP BAM way. Sort of need more positive feedback I suppose.
I just love Ne types.
