If you aren't old enough to enter a marriage with another person, how can you possibly be old enough to make another life commitment?
As the WTS likes to phase it "Beyond the Bloom of Youth". I know I will be facing the same issue with my oldest son, as he is getting pressure from my wife and brothers in the hall, but I am going to put my foot down on it. I am sure it will be the first real fight my wife and I have over my long gradual fade.
