People are surprisingly good at hiding. We hide because we have an image to maintain. We hided because we don't want to spend years trying to take back our identity from identity thieves. We hide because we fear things like the truth or being confronted with the truth.
Sometimes hiding is necessary. Sometimes you need to hole up and come out renewed again.
Many times hiding is just delaying the inevitable: the inevitable reveal, the day or event that you fear.
The one of the tricks as always is knowing when to hide and when not to. A larger trick is knowing that all the hiding in the world will not make the world go away so you have to deal with whatever stuff is left behind.
