Someone commented to say alot of the building aid actually hasn't been delivered and therefore can't be used anyway, but what's the chance this is because the aid cannot get through the rubble that no one's shifting, and if know one moves rubble to then use the building aid it is only going to gather up and cause even more of an obstruction, therefore it'shaving to be held back and sent out in stages.
I don't know how they must feel, but if I had no food and no family left alive I would still be doing everything I could, working towards a goal, but that's just me....I not one for sitting around I get restless.
