Even then he was hesitant and had to phone an Egyptian friend of mine in Australia (the woman who taught me Arabic who I also call my second mother) to verify that I was telling the truth. It can be taken as really rude if you say it to a girl who doesn’t have a playful nature or the right sense of humor.
I have Egyptian male friends whose fathers actually saved up for years to buy their sons an apartment (usually in the same building as their parents) to make it easier for them when they wanted to marry. Never say this to someone you don’t know for obvious reasons.
For Muslims especially there’s the issue of a dowry which can be money, gold and assets.
Because I didn’t have family with me and no one present to confirm who I was or if I could be trusted, the father had to contact Egyptians who knew me back in Australia to verify everything.
This carried the expectation that we intended to get married.
