MBTI Be Damned

I have 2 friends x and y. X is an E*FP (as in MBTI, not sure whether he is N or S) and y an ISTJ. Superficially they are both very dissimilar. One is fun to be with, gregarious, regales you with stories of incidents while the other is quiet, organized, disciplined.

Y is incidentally D's father in https://vbala99.blogspot.com/2018/02/vikram-or-vetaal.html

I found that x and y had something in common. Y has innumerable ailments. No sooner is one ailment kinda cured than he starts mumbling about the next one. He is scared stiff that people might come to believe that he is perfectly fine. He hates that very idea that people should think that she is doing fine. 

X as a young man used to gamble, got into many (i guess dubious) business ventures and ran up a lot of loans. His father would come from his home town to visit X in the city, pay off his son's loans and and ask his son if that's all the loan he, the son has. The son, X, would confirm yes only to bombard his father later with more loans to repay.

X, the FP, gave a lot of distress to his elderly father. After the father helped pay off X's  loan, x will broach the subject about another. And then another.

Y, the more disciplined FJ, would broach about his next ailment or pain, as soon as one was sorted out or addressed. He stood in perennial fear of being deviated healthy. The same way an OBC or SC/ST person might fear being termed a Brahmin and thereby lose all access to subsidy.

I used to feel that deep down both x and y were similar in the amount of pain they gave to the people who supported them.

J or P, it didn't matter.
