Hope she enjoys loneliness.
Agree. I have a sister-in-law like that. Doesn't care much about children, never had any. She's in her senior years now, her husband of seven years or so committed suicide last summer, and she's alone and poor. And estranged from us and the other siblings.
My greatest joy is babysitting my grandchildren almost daily and having everyone gather at my home for parties. Even if the kids drop crumbs everywhere, I don't mind picking up after them at all. I love my family and am never lonely.
All she deserves is many lonely years in a bad nursing home...
