well, i used to have an ENFP best friend, but we kinda fell out because we would have these major, major quarrels after she hurt me & i blew up (or the other way around - it was always a very touchy-feely affair).
it was really annoying, actually, and she was pretty high maintenance - no offence! - though it was really awesome too because she was quirky: read jeffster's post. in the end, though, our communication problems always got back to us.
maybe if you work on the communication a lot, and state straight out how you want us to please you, it'll help so does getting us to open up over the internet! good luck with that.
