Polysemous. When does ambiguity make meaning in a poem?

Words too close to a precipice?
The memory of what the mirror saw?
Snapshot left in a drawer for two decades. No names, no dates on back-of. What to make of?

When the story needs to be told, to be written.


Small dishes with irregularly-cut savories placed in hand's-reach of the hungry. A trace of salt; no trace of ambiguity.
