How would you describe the tone of Frank's diary? How does she

relate to her subject matter?

I assume you're talking about Anne Frank, the teenage girl that wrote a diary during the holocaust. I would describe the tone of her diary as youthful and optimistic, with hints of humour as you would expect from a teenage girl. But at times there are other emotions, such as anger and sadness, as would be expected from a Jewish person in hiding during the holcaust.
