I often hear my oldest son or my youngest son in my oldest daughter's room after bedtime talking and laughing. Always in her room for some reason, where she receives them like a queen. I could remind them that they need to go to bed, and if it goes on too long I do, but I like hearing them enjoy their own relationship and the intimacy that is only available between siblings who have known each other their whole lives and who I have the privilege of providing a little haven for.
@LDS_Dems You can tell this distinction was made by a Protestant because if you moved the goal post a little further you could disqualify all Protestant denominations as not Christian
