Grief is the experience of losing someone close to you: the closer the relationship, the greater the grief. The exact experience of grief is different and unique.
From the early years of childhood, grief has been part of our life. Children even include grief in their imaginative play. Though the play is imaginative, the sense of grief is real, but not totally understood by a small child.
For each one, whether child or adult, grief is uniquely personal. The characteristics of grief are the same, but the depth, breadth, and height are individualized. One could say that grief is a matter of the heart.
