How quickly to bois and new-girls grow up?

How quickly do bois grow up?

There is a strange dichotomy in many of the TG stories – it seems to be accepted in the wider (real) world that girls are mature more quickly than boys – both physically and especially emotionally.

But in the TG-Story world, time after time, the ‘new-girl’ displays skills and abilities far in excess of her age-equivalent girl friends. Two reasons spring to mind - wishful thinking and perhaps that the pressure of being T-in-hiding actually gives such people a speedier maturity.

I would enjoy some feedback - as I feel there is a story here !
