"I have a little shadow that goes in and out with me, And what can be the use of him is more than I can see"

This quote by Robert Louis Stevenson is a metaphor for the idea that we all have a part of ourselves that follows us any place we go. This part of ourselves is often something that we can not discuss or comprehend, but it is constantly there. It is a pointer that we are never ever really alone, even when we feel like we are. The shadow is a representation of our innermost ideas and feelings, and it is something that we can never ever really escape. It is a pointer that we are all linked, which we all have a part of ourselves that is always with us. The quote is a pointer that we must never ever take our innermost ideas and feelings for approved, and that we ought to always aim to understand them.
