"WHEN TO THE SESSIONS OF SWEET SILENT THOUGHT"

When to the sessions of sweet silent thought
I summon up remembrance of things past,
 I sigh the lack of many a thing I sought,
And with old woes new wail my dear time's waste:
 Then 'can' I drown an eye, unused to flow,
 For precious friends hid in death's dateless night,
 And weep afresh love's long since cancell'd woe,
 And moan the expense of many a vanish'd sigh:
Then can I grieve at grievances foregone,
And heavily from woe to woe tell o'er
The sad account of fore-bemoaned moan,
Which I new pay as if not paid before.
But if the while I think on thee, dear friend,
All losses are restored and sorrows end.

(Sonnet XXX)

William Shakespeare
