Bats flit hither and thither

My private moat,
With crocodiles and a boat,
I strap around my neck.

My private protection,
From circled insurrection.
I am safe from attack.

My castles my head.
Flags hoisted all red.
Keep Out or it's the rack.

Deep within, by the fortress ticker
Shadows off my candlewick flicker

A creaky door,
Slams Shut.
(Elsewhere, another reverberates open.)

Shuffle.. shuffle.
'aha! An open door'

A permanent wind breezes,
Through my castles friezes.

Bats flit hither and thither.
