Yeah, I know the thread is old, but I have more trouble with ENFPs than any other type. They're like sirens to me. I'm drawn in by the infectious giggling and having of the fun, but I am invariably caught up in a long talk about feelings. Usually what I have unintentionally done or said to hurt their feelings. Sometimes this is my own bluntness or messed up sense of humor. I fully admit that sometimes what I say comes across way more harshly than it is meant. As a clueless INTP, I'm often completely oblivious about what might offend someone. Many times, however, this is projection by the ENFP, and what I actually said has no logical connection to how they feel about what I said. Time and time again, I've gotten really close to an ENFP only to quietly withdraw when the emote fest becomes too much for me.
For example, I have an ENFP friend who is married to a police officer. Her husband teaches a group of teenage kids who want to eventually become cops. The discussion went off topic and into clubs. I said, "I was in the debate club. No one in the club became a cop." She hears, "I think that debate club kids are really smart, and kids who want to become cops aren't intelligent enough to be a debater." I was quite taken aback, especially considering that her husband and I are friends. This led to a very long discussion about her feelings, which she prompty dropped when she became distracted.
I've found this sort of misinterpretation/projection to be common with the ENFPs I have known. I have a whole lot of fun with them, and I don't mean to be hypercritical. Honestly, ENFPs make me laugh more than any other type. I just have to get away from them sometimes for my own sanity because their emotions can be rather overwhelming.
