A small, thin sparrow was hopping on the ground at the bus station near the library.
On my seat, I saw several cobbles in white or gray color.
A girl sat beside me, dressed in pink skirt and holding another cobble in her hand.
"I got a triangular cobble!" uttered a girl, smiling.
The triangular cobble had light brown streaks around it.
The girl placed the triangular cobble on the wooden seat.
"It is the smallest bird." said the girl, pointing at the small bird on the ground.
"It cannot fly far."
Three birds were chirping. One bird was also small, but looked stronger. One bird was larger but thinner.
Then the three birds flew off, low among the shrubs.
