On seeing an old man's green cords

Old man, where did you get those green cords?
The cut of your green cord slacks sends shivers down my spine
Those graven ruts which fall in lines so smooth and serpentine

The colour of green makes my knees go weak
It’s not like teal or tortoise shell turquoise or mint or leaf
It’s like mossy royal velveteen
It’s brash and brazen, yet endearing when faded

Old man, where did you get those green cords?
Do you think you could get your tailor to taper them in?
As long as they stay up I’ll buy them in any old size
Oh old man, you wear them with such panache and flair
If only I had a pair

Old man, where did you get those green cords?
Old man?
