The customs related to death have arranged social behavior in every part of the world according to religions and traditions. In most cases, mourning is the way in which grief is expressed at the loss of a loved one, and this is shown through outward signs such as clothing, ornaments, and other objects during and after funerals. This behavior demands rigor, such as abstaining from entertainment or activities outside the home.
Years ago, children played in gardens or in the countryside, close to nature, and observed life cycles. They had a closer coexistence with their loved ones: grandparents were accompanied in their illnesses and when they died, funerals were held in their homes. In our time, despite access to media information, medical advances, and constant migration, children have distanced themselves from the knowledge of death and the way in which mourning is experienced throughout life.
