We all had lots of stories of our sad experiences - they mourned the death of my wife with me - but we were hopeful that the children would return.
For me, it was a revelation. There, was revealed a completely different Anne to the child that I had lost. I had no idea of the depths of her thoughts and feelings.
I just can't think how I would go on without children having lost Edith already... It's too upsetting for me to write about them. Naturally, I still hope, and wait, wait, wait.
How could I have known how much it meant for her to see a patch of blue sky, to observe the flying seagulls, or how important that chestnut tree was to her, when she had never shown an interest in nature before. But once she felt like a caged bird, how she longed for it. Even just the thought of the open air gave her comfort, but she kept all these feelings to herself.
I shall remember the look in Margot's eyes all my life.
Most parents don’t know really their children.
I think it is not only important that people go to the Anne Frank House to see the secret annex, but also that they are helped to realise that people are also persecuted today because of their race, religion or political convictions.
I will never forget the moment when Peter van Pels and I saw a group of selected men. Among those men was Peter's father. The men were marched away. Two hours later, a lorry came by, loaded with their clothing.
One day in Auschwitz I became so dispirited that I couldn't carry on. They had given me a beating, which wasn't exactly a pleasant experience. It was on a Sunday, and I said: 'I can't get up'. Then my comrades said: 'That's impossible, you have to get up, otherwise you're lost'. They went to a Dutch doctor, who worked with the German doctor. He came to me in the barracks and said: 'Get up and come to the hospital barracks early tomorrow morning. I'll talk to the German doctor and make sure you are admitted'. Because of that I survived.
There are no walls, no bolts, no locks that anyone can put on your mind.
