I am an english female that speaks, reads and writes perfect english. I have O level english language grade B. I have worked 40 years within the British military where my knowledge of the english language was utilised as a secretary to the colonel of the regiment amongst other job roles. I would very much like to put my inherent skills to use with others, that they might also command the most spoken language in the world.
