I could never say or do that to someone I loved. She did it to save you from "embarrassment" and that's how you repay her. Didn't you ever ask her why she had a missing eye? Maybe then you would of respected her for the amazing woman she was!
It's a choice....don't feel sorry for the parent who chose not to spend time with their kids while they were in elementary, middle and high school. These are the critical years. If you love them you'll find a way.
