Poetic Bloomings -- Baffled

What Could it Be?

My sisters and I, home alone,

The youngest—two, one almost grown.
From dark of night, we couldn’t see.
Kerthunk, kerthunk, what could it be?

The eldest sis scared us the most.

“Perhaps a mischievous ghost!”
A spooky sound, like a heartbeat.
Kerthunk, kerthunk, what could it be?

At seven I didn’t believe.

“There’s no such thing!” I stamped my feet.
“So you go out,” said older three.
Kerthunk, kerthunk, what could it be?

And so I bravely went out there—

A beagle in a rocking chair!
I laughed at them. “What did I see?
Kerthunk, kerthunk, what could it be!”

My sisters and I, home alone

Kerthunk, kerthunk, what could it be?
