Cobbles

After lunch, the gentleman finished his cup of coffee and sat down on the sofa, placing behind him a pillow – the type found in Russian taverns that instead of soft, flexible wool, would be filled with something alarmingly similar to bricks and cobbles.

The old cobbles in the streets have gradually been substituted by asphalt in all cities.

The cobbles lie dormant beneath a layer of asphalt.

The cobbles are also round, which tells us that they are being smoothed as waves carry them up and down the beach, rolling the cobbles against each other and knocking off any sharp or broken edges.
