D-3 Cultural differences

Today, I have been invited to Hussein's sisters' place for some conversation.
My first surprise was that they are living in the flat just above :) My second surprise was that they were actually between 40 and 60 years old, which is something I was not imagining for 3 sisters living together.
They actually still live at their father's house because they are not married. They explained me a woman can only leave her parents' house when she finds the man she'll be spending her life with. The 52 years old one confessed she has not lost hope yet and is confident she'll find an husband soon. The 40 years old asked me to take her in my luggage back to Spain as she thinks it will be easier to find there. She asked me "Do they like fat women there?" ;)
One of Hussein's son was translating for me. He added "Men can leave their parents' house whenever they want; I know it is not fair. But I would not like my sister to live with a man if they are not married, so she will stay with us until she gets married as well".
They asked me about my situation and were happy I was married... They could not understand though, what I was doing here so far away from my husband.
It was definitely a cultural shock!
As usual since I arrived, we shared some traditional food; I love their convivial way to eat all together, all in the same plate, with no forks or knives.
