He only employs his passion who can make no use of his reason.
It Nods and Curtseys and Recovers
by A. E. Housman
It nods and curtseys and recovers
When the wind blows above,
The nettle on the graves of lovers
That hanged themselves for love.
The nettle nods, the wind blows over,
The man, he does not move,
The lover of the grave, the lover
That hanged himself for love.
