My parents are in good health, and they are over 80 years old. Do you want to buy a cemetery in advance? I don't think there is a good chance, because of birth, illness and death. Four people are normal. Each of us will face the day when our parents will find themselves getting older and older. I think it's normal to do your own thing in advance, because old people think so now. Because parents bought it in advance, there is no need to increase the burden on their children. And I can feel at ease. I think this is an excusable thing. There is no distinction between good and bad.
