Yeah...it's a tough one for me, to be honest. I don't get over grief well...it's more a process of bottling than anything resembling healthy...hehe... But it's funny how reactions go... My mother told me a few years ago she planned to be cremated, and despite not being much of a cemetery person, the thought of not being able to "visit" her filled me with sadness. I talked to her about it and she changed her mind - she knows I struggle with it, so she thought she was making an unselfish decision, but enjoyed the idea of being visited - admitting it was a silly thought, as she has no doubt she won't be there.
Burial customs have been a thing as long as human beings have been on earth, and are as varied as the human beings who observe them. The process of saying goodbye is tough, and there is no one size fits all approach.
