Writing memoir is like taking a magnifying spotlight and shine it on certain parts of one’s memories and blow them up for others to see.
It is hard to write a memoir for ourselves not to mention for others. Why? Because we cannot be truthful. Not that we do not want to but we cannot. Our memories tell us things that may not be true and we tend to select the more pleasant or the more politically correct parts and ignore the rest. We do not want to hurt ourselves or others. We put some window dressing like we put on makeup when we go out and do not want to be seen as too colorless. There are many reasons for not being truthful. I personally find it hard to write untruth which is why I do not write my own memoir. I write memoirs for others. They speak and I write. It is different from writing my own. However, even though the onus is on him or her to be truthful I still find it hard when I know it is not her or him at all, this nice person they try to portray. Does this mean I stop writing for them? My answer is no. As long as they put their own names as authors and be accountable for themselves.
I believe the readers know too. Many readers are their friends and relatives. Their colleagues, their bosses, their subordinates, their suppliers and consumers. People who have worked with them and for them. Their church friends and pastors. Their corporate organization and community too. Their husbands, wives and children. So how can anyone think or imagine or fool himself or herself by telling tall tales and believe that the tales will hold water?
When I interviewed someone who was a friend of someone else, I often heard another side of the story. Shall I put them into the book? A question hard to answer.
My advice to young writers and copywriters is be really careful and do research before you agree to write for someone. Always look behind the facade for credibility and integrity of the person concerned. The onus is on you to check before you commit to the writing assignment.
