Working for a "school" like yours in a country like Sudan must be a nightmare. The nightmare is the corrupt and absolutist and autocratic political system there that your "school" apparentl takes advantage of. I suppose that employees at your "fine" school are unable to leave the country if you disagree as an "employer" as is the case in most Arab Islamic countries. I even won't trust you, your "school" and the political system in this country of Islamic fundamentalism for a minute. There are far too many Sudanese refugees in Kenya with many terrible stories of what happened to them to tell; so I would say that Sudan as it looks now is a shithole that nobody should move from outside - neither as a tourist nor as a teacher or other employee.
