Plastic Bottles Filled With Milk

Plastic bottles, filled with milk,
White clouds above, soft as silk

Quite a peculiar sight to perceive
But not the hardest to believe

How did you get here, dear milk bottle?
Did you come by car, speed, full throttle?

Or were you flown here by a little bird?
Over landscapes, see the world?

Or a milkman, was that it?
Dropped off here, and here you sit

Your caps the very brightest red
I pick you up, nod my head

This milk will do for tea just fine
That that wonderful milkman of mine!
