Mermaid’s song

A mermaid sat on rock singing:
A great heart grows
A small heart shrinks
A wise heart soars
An old heart sinks
An open heart learns
A closed heart lies
A warm heart lives
A lonely one dies.
The rock replied:
“Be glad you were made a mermaid
Go where your presence blesses others!”
And at the very moment the rock said this
The mermaid dived
And was swallowed by the sea…
