Yes,I'm the "CHOSEN ONE" with that said I don't have one regret taking care of my mother. I was with her when she passed. I know I did everything to keep her comfortable. Ten years later my dad is 95, he does pretty well living by himself. With that said I am the person who calls the Doctor, shops, clean his house etc.
I have an older brother and younger sister who live closer and don't help. When he goes to his happy hunting ground, I will be OK knowing I did everything to make his life a little easier.
