John Donne
That Time and Absence proves Rather helps than hurts to loves
ABSENCE, hear thou my protestation
  Against thy strength,
  Distance and length:
Do what thou canst for alteration,
  For hearts of truest mettle
  Absence doth join and Time doth settle.
Who loves a mistress of such quality,
  His mind hath found
  Affection's ground
Beyond time, place, and all mortality.
  To hearts that cannot vary
  Absence is present, Time doth tarry.
My senses want their outward motion
  Which now within
  Reason doth win,
Redoubled by her secret notion:
  Like rich men that take pleasure
  In hiding more than handling treasure.
By Absence this good means I gain,
  That I can catch her
  Where none can watch her,
In some close corner of my brain:
  There I embrace and kiss her,
  And so enjoy her and none miss her
