One of the biggest cultural shocks here for me has to be the way in which men and women relate to each other. It is so far removed from the Western world that I am used to.
Men and women are pretty much segregated in Libya, and there seems to be very few women compared to the number of men out on the streets, shopping, at cafes or restaurants. I have not seen one couple showing affection or holding hands in Tripoli but it is SO common to see men being affectionate with each other (not to be confused with homosexuality as that is actually illegal in Libya).
Walking down the street you see men holding hands, with their arms around each other, leaning into each other, stroking each others faces and planting kisses on each others cheeks.
