As a game, I would throw a pebble at an angle to the lake to see how many times it would skip across the lake.

Even though the boy rarely played outside, he didn’t mind if he stepped on a pebble or a leaf with his bare feet.

Ocean water had washed over the pebble countless times so that it was perfectly round and shiny.

Instead of collecting the pointy rocks, the beachgoers would try to find a pebble.

As the bored children walked by, they would throw a pebble into the well and hear the small splash.
