One of the supposed benefits of the ESTp-INFp duality is that the ESTp appreciates the INFp's ability to guide him/her through situations whose consequences he can't foresee. Wikisocion described the ESTp's appreciation for in the following words:
But sometimes the out-of-control ESTp doesn't appreciate the INFp's sobriety and prudence. Case in point:The individual is impulsive but at the same time desiring of not going too far in his impulsiveness and unsure of his own ability in this area, so people who are confident on how far to go and when to stop are admired and their company is desired.
Yesterday I went to a concert with a few ESTps who were very cool people, but who loved to party in an indiscreet fashion. They told me tales of how they averted the police, how they loved talking to the police when they came to break up their parties, how they got really wasted, and so on.
Before we went to the concert they and a bunch of others insisted on having a tailgate party. There's nothing wrong with that, as long as the property on which you're having it permits it. They had one in a parking lot whose owner expressly told us that drinking was not permitted. I was one of the three drivers on the trip, but the party was held in another person's car because I damn sure wasn't going to have one in mine. So, in a nutshell, we're in a fairly dangerous neighborhood near the concert venue having a tailgate party on a property that doesn't allow drinking. I was FREAKING OUT. And I was with a bunch of ESTps, ESFps, and ENTjs who really didn't seem to give a damn. Luckily for them they didn't get caught, but the whole time I was thinking in my head, "we're either going to get caught and kicked out, caught and arrested, or robbed by a nearby hoodlum who sees a bunch of vulnerable, stupid drunk kids." I don't drink, but I was still afraid of being arrested because of my association with people who did.
The joke on the trip was that I was the "paranoid" one. One of my ESTp friends told me that he was the exact opposite of me, and that he just "didn't worry" about things. I envied him and feared for him at the same time.
So, my point is, how do you EFFECTIVELY tell an ESTp that what he's doing is stupid and unsafe? I need to grow more of a spine so that I can say stuff like that openly, but I just get scared because I know that people don't like being told what to do (I HATE it when my INFp mom tells me that what I'm doing is unsafe). Any suggestions?
