It’s very obvious, I may be the only one that hasn’t thought of this before… I have long been amazed at Yemenis’ ability and desire to make lots and lots of noise. Yelling, shouting, screaming are all considered an appropriate method of communication in the street. People make noises to just amuse themselves, the really loud whistle you might use to call a dog is a favorite one here. Horns are blown constantly, the trash truck has a deafening siren, and weddings are public nuisances with their blaring music and sounds.
It occured to me that every one of these people has, from the time of their birth, been yelled at 5 times a day starting around 4AM. In their minds, being loud and shouting is not only a legitimate way of communicating, it is seen as a positive force in their lives. Being loud is a way of being “right”, just like the calls to prayer… No wonder they enjoy being so loud..
