How the hell am I supposed to decide if I'm J or j. I think there are more gradients in between "J out the A" and "questionable J." I'm definitely J but more so in my dealings with people. When it comes to anything else, especially keeping a clean environment, I'm very P. I'm really only ever on-time to official things like work and appointments. When it comes to going to a friends house, I don't even look at the clock. I take my sweet ass time. Overall, I'd say my J is kind of like being libertarian. Conservative and J-like in some ways, Liberal in others.
Other than that rant, I'm kind of sort of the oldest. My mom had a kid in her previous marriage who I hadn't met till recently (he's the oldest, probably an ESFJ, and 100% wienerboy.) I'm eNFj overall and my younger sis is EsTJ. So I don't think that there's much to this theory. Rather than nurture this is most likely nature. The more assertive sperm (you know the ones that have plans and wear little watches) were the ones that got there first and made us babies!
