[نايف مهاب المصرى]

I'd like to tell anyone who is not specialized in English , shouldn't give his opinion . Secondly , to remind you that the book is American and is no longer being taught there now due to being old and not coping with the modern age , taken and adapted by two careless ladies for the Egyptians , not caring for our customs and our examples , our priors and habits ....and so on , they just changed some kind of clothes and names .
concerning the question
are you finished?
slang american
have you finished ?
is the right one but the other one is right for the americans and not for the language
