FORGET not yet the tried intent
Of such a truth as I have meant;
My great travail so gladly spent,
Forget not yet!

Forget not yet when first began
The weary life ye know, since whan
The suit, the service, none tell can;
Forget not yet!

Forget not yet the great assays,
The cruel wrong, the scornful ways,
The painful patience in delays,
Forget not yet!

Forget not! O, forget not this!--
How long ago hath been, and is,
The mind that never meant amiss--
Forget not yet!

Forget not then thine own approved,
The which so long hath thee so loved,
Whose steadfast faith yet never moved:
Forget not this!

Sir Thomas Wyatt
