Not a single pair of eyes was on her.

How many offspring had they hoped to produce from a single human pair?

Meant only to be caught by a single pair of ears, no other.

Blow does not own a single pair of flat shoes.

Outside, the single pair of running feet were pounding closer.

Then, squinting through a single pair of eyes, the two young women watched the sun rise.

Finally, she heard a single pair of footsteps walk across the floor to open the inn door.

The original proposal had only a single pair of stations.

She begins counting, instantly able to picture every single pair in her mind's eye.

From there a single pair of footprints continued along the path.
