I will be cremated after my organs are donated. Then my ashes will be spread around the perimeter of my property.
I say if one wants to pay respects to a person to do so in life. To me it is unnatural to embalm a person and lay him/her out on display. It doesn't feel like the person I once knew and overall it all seems so surreal. I respect each person's decision to make their own choice though.
My parents already prepaid for their funerals and have a stone already up with etching of their faces on them. At my grandmother's funeral my mother told everyone to gather around grandma's casket for a group picture. Again, surreal and odd. But it made my mother happy so that's all that matters.
