I actually think this thread is ridiculous @CounsellorTroi although it was bound to be started by someone.
There are numerous ways of being a 'bad ' parent. Posters have described those and anyone here knows them all as they crop up daily.
Being older and dying perhaps when you child is 25 or 30 is not IMO one of the worst.
I haven't seen anyone here say what they think is an acceptable age for a mother to die.
I come back to the same point which none of the critics of JPJ seem to answer.
Is parenting simply measured in the years you have with your child, or the time and love you give them when you are around?
I'm sure they will all say 'Both'.
But that doesn't mean there is no room for women to do things differently to you.
In many societies, older age is considered something to be revered and older generations are regarded far more highly than here in the West.
