Bleak or what?
Good points, TM.
Look, for instance, at children in care who are officially on their own at 16; many of them join the forces which then becomes their family. On discharge they're lost and become the homeless and the drifters who so often end up in jail. The various ship, regimental and squadron associations and the RBL and others do their best to help but they can only work with the ones they know about. Those who, for reasons various - often linked with perceived authority figures - do not come forward are the most vulnerable.
What do we do for them? Not a lot.
