This diary is a gem. Never before, I believe, has anything been written enabling us to see so clearly into the soul of a young girl, belonging to our social and cultural stratum, during the years of puberal development. We are shown how the sentiments pass from the simple egoism of childhood to attain maturity; how the relationships to parents and other members of the family first shape themselves, and how they gradually become more serious and more intimate; how friendships are formed and broken. We are shown the dawn of love, feeling out towards its first objects.
