My sister-in-law would disagree with you.
She loved my brother very much and is devastated now that he is dead.
She not only worked, she would go to work by 7am and usually be home by 4 pm.
The past 3 years were different because my brother was battling cancer. She took off of work when she needed to take care of him.
She loved him for who he was, and he loved her for who she was.
