Grief is unique and deeply individual.
People all express grief differently.
For many people grief is silence, quiet, soft, and nonverbal. I have seen many people process grief in my work as a chaplain. Many families and patients I see do not only express grief through external actions like crying. It should not surprise anyone that some families are never allowed to show or express their feelings. Many were taught to never show their tears or do never never cry in public. Yet, people are still grieving and hurting even when they are not expressing their grief externally.
So do not put grief in a box.
Do not judge others grief.
Be better at allowing people to process their grief.
Grief has no rules.
So may we let people grieve their own way.
