Afraid of the dark? This picture book is about not fighting and resisting unnecessarily when one is faced with something that one cannot change. Being afraid of the dark is a very common part of childhood for children, and it can be a challenge for them to be brave, but the darkness will eventually pass. In fact, adults should also reflect on how to face the unchangeable with the right mindset. I hope this book will convey the idea of following the objective laws of nature.
