There are no building codes in Egypt, at least not that I'm aware of, and people are free to use their whims and imaginations when it comes to decoration. The villagers seem to have pretty colourful imaginations.
I came to Egypt as the wife of an Egyptian/Canadian businessman and the mother of our children in the late 80's. My husband is no longer with us, the children are pursuing careers abroad, but Egypt is still my home, albeit, a rural rather than urban one. You can reach me at msgabbani at gmail.com
