In Vienna public transport and the streets are full with pupils during the week. Its surprising that in the English speaking world people would not allow their children such a nice and important step of early emancipation. I think its an important thing to learn for children to navigate on their own and also to come home when they are supposed to on their own.There are other nations where kids are not driven everywhere by their parents and protected in little cotton wool bundles. The Anglo-Saxon world is very, very guilty of doing this though. The UK, USA, Canada, Australia and New Zealand all seem to have this fear culture surrounding children and their activities.
