"Shadows" brings message that can be interpreted differently by each one. But in general it shows that everyone has it's own shadows (WOW, SERIOUSLY?). Yep, i mean shadows in an abstract way, everyone has something that pokes you, it may be a troubled past, a wrong choice, bad attitudes or whatever it is.
But in the end we learn to deal with this, these are things that will be attached to our story but don't need to be part of our existence, so it's better to learn with these things. That's all, would love to hear from you too.
