One of my favorite writers, Theodore Darlrymple writes on The Pains of Memory
Most of my mother's suffering was unknown to me. Of course, there were people who suffered much worse than she: she never saw the inside of a concentration or extermination camp, for example. But yet, never to have seen her parents again, to have emigrated, friendless and penniless, to another country at the age of 17, and to have lost her fiancé killed in a war: that is enough for any human being.
She dealt with it by silence. When the Mayor of Berlin invited her back to Berlin towards the end of her life, she accepted, much to my surprise; and she pored over a map of the city, pointing out to me were she lived and where she went to school. When she got there, the streets were there, but she recognised nothing; bombs had razed everything to the ground.
I offered to go with her, but she went on her own. It is an unfashionable truth in these times of psychobabble and emotional intelligence, but a trouble shared is often a trouble doubled. She wanted all that she had seen, and all that she suffered, to go with her to the grave, for she was of the pessimistic view that man never learns, at least from the experience of others. I do not entirely agree, and wish she had said more; but she had earned the right to silence.
