Freddie
Plenty of husbands don't know their wives well enough. Furthermore, you knew me quite well before the "I do"s. Your argument is invalid.
She could stay with a friend, if she chose. Or she could come with us. You can't deny it's educational and she might enjoy it. The Sergievsky girls seemed to, and David and Lucy both said they traveled with us. It's an option.
Furthermore, Freddie, she's not your typical teenager. Yes, she's stubborn and opinionated. But you ought to be used to that by now. She's smart, and thoughtful, and so very mature for her age. Look, I'm not saying it's a definite. She's obstinate, she doesn't want to be taken care of by strangers and I don't particularly blame her. But if we can help at all...I'd like to.
