Blowin' in the wind

Porque cada vez mais as respostas a muitas interrogações são fugidias, longínquas ou indefinidas...

How many roads must a man walk down
Before they call him a man
How many seas must a white dove sail
Before she sleeps in the sand
How many times must cannon balls fly
Before they're forever banned
The answer my friend is blowing in the wind
The answer is blowing in the wind

How many times must a man look up
Before he sees the sky
How many ears must one man have
Before he can hear people cry
How many deaths will it take till he knows
That too many people have died
The answer my friend is blowing in the wind
The answer is blowing in the wind

How many years can a mountain exist
Before it is washed to the sea
How many years can some people exist
Before they're allowed to be free
How many times can a man turn his head
And pretend that he just doesn't see
The answer my friend is blowing in the wind
The answer is blowing in the wind

(Bob Dylan)
