Sonnet 51

Thus can my love excuse the slow offence

Of my dull bearer when from thee I speed:

From where thou art why should I haste me thence?

Till I return, of posting is no need.

O, what excuse will my poor beast then find,

When swift extremity can seem but slow?

Then should I spur, though mounted on the wind,

In winged speed no motion shall I know:

Then can no horse with my desire keep pace;

Therefore desire, of perfect'st love being made,

Shall neigh—no dull flesh—in his fiery race;

But love, for love, thus shall excuse my jade,—

      'Since from thee going he went wilful-slow,

      Towards thee I'll run and give him leave to go.'
