Ojos que no ven corazon que no siente

• Noches de Moscú ≅ Moscow Nights Song
• Ojos que no ven corazon que no siente ≅ Out of sight, out of mind

Si uno no ve algo por un período prolongado de tiempo, uno tiende a olvidarse de él.

Out of sight, out of mind - If one doesn't see something for an extended period of time, one tends to forget about it.

• Salt water and absence wash away love.
  
• What the eye sees not, the heart craves not.
  
• What the eye doesn't see, the heart doesn't grieve over.
  
• Absence makes the heart grow fonder.
