So your sister was ready for marriage at 9? If an adult male had walked your fourth-grade sister home from school one day and told you and your mother that he wanted to marry her and put her in a house and let her have his child .... you would have found that appropriate? And you would have considered other factors besides her age while mulling his proposal? Just asking. *edit..and don't cop out behind "It's illegal in my country"...this is a hypothetical question. You say "mature 9-year-old" types are suitable for marriage and child bearing...you also say your sister was one of them. I would only like to know if you could envision tolerating her marrying a man as a fourth-grader and having his baby.
