To borrow WORDSWOTH'S lines---- man has often reason to lament "what man has made of man".When you watch a bird fly from the tree,a squirrel jumping the branches and your children forced off the sand and trees outside to the text books thrusted up on thier lap...which gives you more joy ?Has not man complicated life for himself ?In the nomadic life I do not think mentally challenged people would have been an issue... but today they do not fit in to our scheme of things.and so are put off in an asylum ..far removed from our eyes and thought.. so that we can escape the feel of guilt.
