Surely you recognize how ridiculous it is to give parenting advice from a teenager's perspective. Parents have been teenagers. Teenagers (at least at the heart of this discussion) have not been parents.
Not at all. With the powers of reflection and self-consideration, I can think back to how I was raised and make judgement calls on the merits of various parenting techniques that I experienced.
Presumably, in the case of first children, this is what parents have been doing since the dawn of time.
