What of a Hatter?
(If madness were comparable to a pot of tea...)

Beginning simply, still and sound as water in a kettle
His mind contained, grew restless, tempted madness there to meddle
At first a spark, then fire burned conventions of his mind
Where sanity remained entrapped, madness was unconfined
Thoughts grew inside his hallowed head, but died when not maintained
The bitter leaves of knowledge dried, and leaves, the water stained

And so The Hatter pours a cup, and lifts it to his lips,
He takes his madness casually, in small and careful sips,
"More sugar?!" Hatter asks the girl who hesitates to drink,
"The more diluted madness is, the harder it is to think!"
"Enough!" she said, then called him mad, and left the man behind,
"Be careful Alice," Hatter warned, "It's you whose lost your mind"
