I have nothing to add from a relationship stand point....however I would use extreme caution with the kids. I personally think they will end up finding out one way or the other and so will others so keep that in mind. you didn't say how old...13 or 19 huge spread and huge difference. I think younger kids 5 -7 and perhaps older would be better....but the older is just speculation on my part. My kids are under 13.....oldest is a girl. Gender could play a role too but again have no way of knowing......as a coach for some of my kids teams I see wide differences in how each gender reacts to same issues. I guess what Im saying is if you have older boy it may not be that big of a deal. Younger girls......that I can say with confidence has the potential to be a very big deal.
Good luck D
