Perhaps this is just an individual problem, but I feel like I bore ENFJs quite easily. (Any other INFPs feel this way?)
They seem so interested at first. I feel completely comfortable to be myself. And after I'm done telling them my life story (how did you get me to do that by the way?

). I feel like I have nothing more to say to them that they might find remotely interesting, and yet I want to keep talking to them, being close to them. I want to be around them, perhaps out of need to feel as accepted as they often make me feel.
It often times makes me wonder: really, what's in it for you guys? It seems you are so busy discovering the INFP, who is going to discover you? How can I make you feel as loved as you make me feel?
After the initial, "I'd like to get to know you" phase wears off, I feel so suddenly like I have to run after the ENFJ, or they will forever become a vanishing form on that rapidly fleeing train that is their life.
