学生时代，一首“随风飘去”让我知道Bob。911时，每晚

和NYU的朋友去Washington Square park唱得最多的一首歌也是它。。。
How many times must a man look up
Before he can see the sky?
Yes, 'n' how many ears must one man have
Before he can hear people cry?
Yes, 'n'and how many deaths will it take till he knows
That too many people have died?
The answer, my friend, is blowin' in the wind,
The answer is blowin' in the wind.
