My kids don't get to date until they're 16, and no official boyfriends or girlfriends. Group dates only.
It worked out well for the boys.
My daughter....I've been telling her from birth that she doesn't get a boyfriend period as long as she's in this town, she has to wait until she graduates. That's not to say she can't go out with her friends and go to dates, but I want it made really REALLY clear that she's not to entertain any sort of dating thoughts with anyone in this berg.
Or at the reservation, where chances are anyone she would go out with would be VERY closely related.
