why so hue n cry, everyone has to die one day, she too died, there's always a reason to die, it may be hunger, or overeating or organ failures,.....
what happens afterwards is NO concern to her,
just a civic mistake by her neighbors to not further investigate foul smell and decompose dead body;
.....No reason to overplay emotions!!
I do agree to take care of parents/old people while they're alive if they wish to, if not like this lady, let them enjoy their life in their way.
