(Third times a charm)
Its interesting what you see on the bus sometimes.
It was near midday and the bus was half empty.
About halfway to my destination, the two ladies who had rushed on at the last minute with strollers and who sat near the middle of the bus, rang the bell.
As the bus was lowered and they started to go down the bus aisle to exit at the front, I absentmindedly noticed that in the seat next to where one of the ladies had been sitting was a light scarf.
I got ready to shout something from my perch at the back of the bus when all of a sudden another lady who was sitting across from the vacated seat swiftly got up and sat next to the scarf.
