My first long-term girlfriend's family lived in central Oregon, and we'd go down there from Seattle periodically to visit. You know how there are moments when your viewpoint is irrevocably changed? The first time you broke a bone or burned yourself, for instance. Such events grant you an awareness that's sharp as a razor, even if only for a little bit. Such was my experience, visiting her parents, after she told me she'd been molested by one of her mother's brothers. She told her folks about it when she was about 21, and they'd immediately dismissed it as impossible.
Her abuser had told her they wouldn't believe her.
I could never look at them the same way again.
When I think back on it, fully a quarter of my friends, male and female, have suffered either sexual or physical abuse, or both. If you wonder why, as I did, part of the answer is in what I just wrote. Guilt can cause us to do terrible things. It can make us deaf to someone's pain. Denial breeds silence, which breeds more hurt. This is a crime, but apathy's worse. If you know someone who's been abused, let them know you give a damn. At least do that much. Encourage them to seek help if the damage is pulling them under.
