Otto Frank got an anonymous message right after the war that said this person was responsible.
I’m not Jewish or German or Dutch; I just think the wrong people could use such an unsubstantiated allegation in the wrong way (similar to people posting - accurately - that blacks were sold to Europeans by other blacks).
I visited the Ann Frank House when I was 13, the same age she was when she began her diary. I had read her diary a couple of years before that.
The most striking thing was the *complete silence*. All those visitors slowly shuffling through, and all you could hear were their muffled footsteps. No one spoke a word. I will never forget it.
