In "As Long As You Need," author J.S. Park writes that "Grief is not about letting go, but about letting in." Letting in sorrow, letting in anger, and especially letting in other people who can be WITH us in our pain. This episode is about all kinds of grief—not merely the grief of losing a loved one. One of Joon Park's main points is that we often experience loneliness in the midst of our sorrow and pain. He says, "It is possible to be in a room full of people, but feel more lonely than if the room had been empty. It is to be unseen. Unseen by those close to you is in some ways worse than having no one see you."
