Once upon a time in a sea far away there was a beach where the mermaids once played. But then one day, when a mermaid was laying on the hot, sunny sand, a boy spotted her.
“Mom! Dad! I just saw a mermaid!”
“Where?!” they both said.
“Laying on the sand. But please don’t tell.”
Later that leavening was a surprise. He saw her on the sand again. The boy and the mermaid became best friends. The end.
