I was blogging on a really nice blog about Egypt called whazzupegypt and its author posted a thread about English speakers in Egypt, and she posted that it would be really hard to do your daily tasks in Cairo only speaking in English, to a cab driver, to a customer, anything you normally do.
Well as a foreign visitor to Cairo I think that would be easy to try out!! but being an Egyptian and trying that!!?......... Well that's something else, anyway I liked the idea and decided to give it a shot.
The results were great almost everybody I spoke to responded really well, the taxi driver, the cashier and even a police man they all could communicate to an acceptable standard.
By the way I'm an Egyptian, but I speak English as good as a New Yorker, Maybe try it out yourself waiting for your story
