Enui, the great slayer of civilizations

Tired Tim
by Walter de la Mare

Poor tired Tim! It's sad for him.
He lags the long bright morning through,
Ever so tired of nothing to do;
He moons and mopes the livelong day,

Nothing to think about, nothing to say;
Up to bed with his candle to creep,
Too tired to yawn; too tired to sleep:
Poor tired Tim! It's sad for him.

The very poetical definition of enui, the great slayer of civilizations.
