Grey is a rain cloud about to burst
It's a silver lining that's been tarnished
By endless stormy weather
Grey is a hard stone
It's a treeless mountaintop
It's emptiness and solitude
Grey is the head of a sledgehammer
Shattering a boulder
Into small manageable fragments
Grey is a sheet of rain
It's Mother Nature's equalizer
It's the handle of an umbrella being extended
Grey is a sigh of relief
