A hurrying, blonde ponytail swings back and forth. An unzipped black coat trails behind a mother, running with her three daughters.
The youngest sleeps in the whizzing, black pram, in front of the toddler perched on the buddy seat. The pre-schooler, hair flying back, smiles with glee as her little legs pump against the ground and her small fingers cling to the handle.
All four are swept up in a moment of exhilaration and imagination. They are a racing car, a rocket soaring to the moon, they are unicorns galloping over a rainbow.
They are also late for the bus.
