I agree with you Lofftie - children dont learn these lessons at nursery - they learn them at home, with family and friends. They have to learn at nursery - because all family and friends are out working their socks off to pay for a roof over their heads and food on the table.
If I were PM for the day, I would round up all homeless people, give them a hot bath, good hearty meals for the day, clean fresh clothes and bedding, and open up halls and community centres so they all had somewhere safe and warm to sleep each night.
