JDHF:
Tell your kids the one thing they'll NEVER hear from the WT:
"Honey, I really don't know. But you know what? Sometimes it's OK not to know. We will never have all the answers in this life. If we did, we'd be Jehovah. In fact, sometimes it's better NOT to have answers than answers that turn out to be wrong, or we knew deep inside were wrong all along. But the important thing is that I love you and will be there for you no matter what!"
Just be honest and tell her what's in your heart. You don't have to say exactly what I did, obviously, but you get the gist of where I'm coming from. Answers from the heart, given to people who still have hearts, will usually eventually win out over "pat" or phony canned answers, especially when the person being given the pat answers realizes those answers are subject to change at any moment.
