Cuckoo-ed

There's a koel
outside my window,
And she's cuckoo.

She's merciless,
the Diva.
A veritable Castafiore,
she pitches her song
deep into the night,
Shattering my dreams.
Like her eponymous clock,
every quarter hour
past two.

She might be another insomniac,
lonelier at night.
A nightbird.
An aberration,
Who sings
of love lost
or a heart halved.

But if you ask me,
I'm kind of certain
she's a sadist.
A cuckoo;
Part of the cosmic conspiracy
to never let me sleep.
To drive me cuckoo,
Too.
