A blonde woman, black t-shirt, locks in a stroller and sits side-on to the little window. Big, fun-shaped glasses on her forehead. She bends forward into the aisle, impossibly low, stretching one arm to infinity. Faded blue jeans with denim hacked from a thigh. Short sleeves. She straightens and shuffles back on her bottom, but the rucksack stops her going all the way.
Grey-blue straps on black.
Bending again, almost to the floor, she rises with a picture book and hands it back.
'Bah!' she says. 'Bah! Bah!'
The stroller squeaks in delight.
Later, head turned, she drags elastic all the way down through rivers of blonde resistance. And shakes her head. And checks each shoulder. And brushes it with a hand.
