I will give you a few clues about when the curse will strike. One, your daughter will become more moody, almost like its all of a sudden. Two, she will likely have started developing breasts.
Well, she's not budding yet, but she has been quicker to emotional outbursts in recent months (though that sort of thing isn't unusual for her anyway).
At least my wife has talked to her about "crossing over", so she probably won't go into shock about it when it does happen.
After she's done "crossing over" I think I want to step in and be a part of the growing up conversations. Right now, I'm leaving it to Mom.
I've got the three boys to deal with, which is a whole 'nother world.
