Classic Poem

Why could you not come? For what reason
could you not come?
On your way, did they build a fortress of
cast iron, a wall within the fortress, and
a house within the wall, then did they put
a chest within the house, a box within
the chest, and bind you in the box,
locking it firmly with a lock, of
dragon and turtle design, on a double bolt?
Why do you not come?
There are thirty days in a month, will there
not be one day you come to me?
