You say 'Thank you very much for the offer, but I'm afraid I've already accepted a job with another company' They'd have known you would be looking elsewhere for jobs and won;t be upset that you turn them down. After all - they'd have interviewed more then you, and they'll just go to the next best candidate.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
