Well you’ve cracked the sky, scrapers fill the air.
Will you keep on building higher
’til there’s no more room up there?
Will you make us laugh, will you make us cry?
Will you tell us when to live, will you tell us when to die?
I know we’ve come a long way,
We’re changing day to day,
But tell me, where do the children play?
– Cat Stevens, “Where Do the Children Play?”
