How about I watched the light leave her eyes?
Why did you watch the light leave her eyes?
I was in a car when she passed and I didn't care if she died.
It sounds like you have not accepted your grief. It is generally accepted than when someone dies that you grieve them. You should seek out counseling.
I don't have time for such things and besides, she was so annoying at the end. She would not shut up and made sure I look at her fucking ugly face as she took her last breath.
It's important to take the time to grieve when someone dies. This can ensure that you heal and begin moving forward.
