This was read at a memorial service at my school for a student who was murdered.
It's saying.. you might not be able to see the person you've lost anymore, but there are others who can..
"I am standing on the sea shore, a ship sails and spreads her white sails to the morning breeze and starts for the ocean. She is an object of beauty and I stand watching her till atlast she fades on the horizon and someone at my side says: 'She is gone!'
Gone where? Gone from my sight, that is all; she is just as large in the masts, hulls and spars as when I last saw her; and just as able to bear her load of living freight to its destination.
The diminished size and loss of sight is in me, not in her; and just at the moment when someone at my side says, 'She is gone,' there are others who are watching her coming, and other voices take up a glad shout,
"There she comes!"
hope this helps xxxx
