A friend in Cairo said that she woke up the other morning to the sound of helicopters. Violence has happened in parts of the city, many incidents that are not making it to the international media platforms. Much of this is a continuation of the rapes and attacks on women - normally not something publicized or talked about as acts of war and savagery in any country of the world, which they are. One clash happened over the Nile River, on a bridge - consider the spirit stories of that river - the serpent God that lives underneath is in opposition to the sun God above.
Other parts of the city are completely safe and calm and people are going about their daily lives with a normal face, another friend told me when he'd gone to a meeting at a cafe before he flew out. It is clear that the last two years have enabled Egyptians to keep moving forward, even in the midst of uncertain change.
