He is an alien for sure. Whilst my mother is an INTP and my brother is an INTJ like me, he is an E something??
He drains us totally and very good at laying guilt trips. He is a bit of an enigma.
He is secretive with finances and lives totally in the moment with money. Doesn't save but procures money somehow.
He becomes emotional like he is drawn back to a time when explaining about an argument about something which happened a long time ago.
He is loyal with his family and likes to "take charge"
he has a way of seeing into people, he is aware of hidden agendas people may have
he is very intelligent and well read
he is manipulative.
he will ask you to "help" him with a job which take an awful long time with you just standing holding something up while he wanders around doing something equally useless. NB not sure if it's relevant but annoys the crap out of the rest of the family.
He is magnanimous and altruistic while leaving himself and us included without resources.....such as taking up volunteer work whilst his wife is pregnant.
If any family members are in trouble (which is very rare) he will take charge and rush to rescue at the ready (we don't usually tell him if we have any glean of trouble)
He will often criticise to the point of madness anything and everything.
He is social and talkative....it seems like he is desperate for company a lot. He will seek out company even if he knows the company is not good company.
