‘…we also know that we shall remain inconsolable and will never find a substitute, no matter what may fill the gap, even if it be filled completely, it nevertheless remains something else. And actually, this is how it should be…it is the only way of perpetuating that love that we do not want to relinquish.’

Sigmund Freud, in a letter to a friend after the death of his daughter.
