Well Segmund, maybe you are right. Maybe this society is simply more realistic and pragmatic about the reality of the situation.
I really can't compare, as I have never heard anything like this in my society...I know a few people who see and are married to a blind person,none of them were prisoners though. But in general, I do not know what the situation of blind women concerning marriage in my society is ....I do know many of them are independent and work though.
