A lady or guy could say that she wants happiness in a man before she can marry him or that he wants fulfilment in a woman, who are we to define happiness or fulfilment for them? For God sake, marriage is about the two people involved, not even the in-laws or ever meddling friends. The danger in the argument of 'right' age for marriage is this- it mistakes age for exposure and maturity but that is a not well conceived one.
