A tiny little thread
Slowly trailing from my body
Filled with depression and dread
It roams around, inspecting the world gravely

Sees all the happy people everywhere
But it doesn't know what's happiness
Smiles on their faces, here and there
All it understands is sadness

One by one, the infection spreads
People realise what is real sadness
Noticing the despair even when unsaid
Everything and everyone is madness
