On sunny days we are a pair
But if it’s dull my pal’s not there
Sometimes he’s short and sometimes long
Sometimes he’s weak and sometimes strong
Though my pace be fast or slow
He follows me where’re I go
He’s at my side on country walks
Though always silent, never talks
I never see my pal at night
But only when the day is bright
Some days he’s never by my side
Is he hiding, has he died?
He can be black and can be grey
Though he was mostly grey today
His monochrome could not be duller
Could he not appear in colour?
By now the reader surely knows
My pal revealed as just shadows!
