Why are you yelling?

Sometimes different cultures do things a different way...
I think I heard somewhere that the Jewish culture repeats things to signify importance - "Holy, holy, holy is the Lord God Almighty"
Just learned that the Gabonese relate the volume of the voice with the importance of the message. This comes from when the chief (pronounced chef) comes through the village yelling something so that everyone could hear.
So this is why they yell sometimes during prayer. Everyone prays during prayer "preons a Dieu"... then one person usually closes the prayer time. But often during prayer their will be a few people praying louder than others... I always thought - do they think God is hard of hearing?
No, it turns out that they are just passionate and want to convey the importance of their prayer. I like learning these cultural differences... to see things the way they see them and not from my American colored glasses. And that our way or their way isn't necessarily better or worse it's just different.
