Categorizing Silence Poem by D.N. Rebb

There are two types of silence
The one where the room is quiet
But you hear all the details
The clock ticking,
Dog barking down the street,
A truck engine braking,
Neighbor above flushing his toilet
And then there is the unusual silence
When you're in a room full of bedlam
Brimming with noise pollution
Conversation over conversation
Creating continuous static
Such emotional turmoil
And yet, you hear nothing
But preoccupied silence
