Is there reason to this Rhyme?

Two white shirts on the washing line
Were flapping high and drying,
When on the clothes peg next to them
A small sock started crying;

And as its tears splashed to the ground
Like rain drops, pitter-patter,
A shirt said: 'Why the weepies, sock?
Whatever is the matter?'

'I'm sorry,' sniffed the sock, looking
From one shirt to the other,
'But how would you feel if the wind
Had carried off your brother?'
