I agree Leon, and I'd like to add to that bro/sis reference.<quoted text>
There are references to Jesus as the son of God in the Bible.
The word 'son' has different interpretations.
It can be said that we are all 'Gods children' so we are all 'sons' and 'daughters' in that sense.
I digress to note that many Iranian men love to ask (usually untouchable) women to be their 'sister'. A cynic would say that is an opportunistic attempt to keep in touch with a beautiful woman who more often than not has shunned the advances of that man!
My own daughter has noted this practice.
Indeed I have seen some 'sisters' treat their new 'brothers' terribly and vice versa!
in the presence of my wife I was encouraged to ask her friend to be my sister.
The bro sis relationship lasted until she stole from my family. Some sister!!!
It's also used a lot in the non-Muslim African American community, probably as an unifying term within that culture, but at the same time they call their women ho's (whores).
This brother/sister BS probably started in the Catholic Church centuries ago when celibacy was the rule of the day. Soo when a randy monk glanced over at the Rev. Mother, bending over picking turnips, he immediately realised that he was thinking incestuous thoughts and rushed over to his confessor for absolution for his unnatural desires, but not until he had described in minute detail every nuance of his fantasy with the Rev. Mother.
My Iranian wife tells me that the custom of calling another woman 'Sister'(only since the Revolution) doesn't mean that you accept her into your family, it's just a way of addressing a stranger in the street if you don't know her name.
Do you have any connections with Iranians Leon?
