Otherness Quotes (page 132)
When friends speak overmuch of times gone by, often it's because they sense their present time is turning them from friends to strangers. Long before the moment came to say goodbye, I think, we said goodbye in other words and ways and silences. Then when the moment came for it at last, we didn't say it as should be said by friends. So now at last, dear Mouse, with many, many years between: goodbye.
Frederick Buechner
