That was 1969 and my mom didn't see me as "helpless". I think she figured I could get away from him if I wanted but that was not the point. It sure made sex seem dirty and ugly until I got older. I only saw him one more time after that. So I did a good job of avoiding him but my parents took vacations with them and everything. (see how my mom didn't want to rock the boat?) And, yes, no stupid excuse like "that's just how they are". I hear it all the time about my brother-in-law who has a blatant lie come out of his mouth every 5 minutes. And the whole family says, "that's just how he is". 🤮
