Oh dear…., Jim..!! What have you been up to….
If it was something like a one night stand then she may not get D’fd. There was a case like that in the hall that I used to go to. She did go onto marry the person she got involved with and they are still together. He never became a JW but she was a talking point for a long time, severely frowned upon. But if it was an ongoing thing, and she got in the club that way then she would be put out for sure.
But if she is 16 then she might not be baptised, and therefore would not come under those rules as such, although it might damage the fathers position, if he is in any standing.
Big hello to you BTW. You did well not to become a JW. Well done.
