The elf and the unconsoled ghost

Once upon a time, Etwas the Elf was running through the forests of tall grass, under the canopies of clover and around the stems of tall flowers when she met a ghost, hovering above a low stump, spectral head slumped onto its chest.

"What's the matter, um, Mr. or Ms. Ghost?" Etwas gently inquired.

"Boo," answered the spirit.

Etwas sat down in the dirt besides the ghost.  After a time had gone by, Etwas looked up at and through the ghost.  "Nice day, huh?"

"Boo."

Another interval passed before the elf spoke again.  "I can't quite tell.  Do you have a tail?"

"Boo."

There was another long time that the elf and the ghost sat silently.  Finally the ghost rattled and groaned and asked "Doooooo yooooouuu haaaaaave a hooooorse?"

"I have a butterfly," chirped Etwas.  "Want to go for a ride?"

"OK." answered the ghost.  Etwas came back a little while later on Rascal and the ghost soared along as the trio toured the southern coast and chased a few sheep.  And ever since then, Etwas has been as patient with the quiet as she is impatient with the (other) noisy.
