Hello ALL! I read this book the 1st time when I was 13 years old, when I finished it, I read it again. I have read it numerous times since, I still to this day have my original copy from 1973, I did revisit it a bit ago and binged the whole book in 24 hours. It was and still is a good read, even though it is not a real diary, it is very relatable! There is also a movie that was released in 1973 I have seen that many times as well.
