Put no difference in your tone, wear no forced air of solemnity or sorrow. Laugh as we always laughed at the little jokes we enjoyed together. Play, smile, think of me, pray for me. Let my name be ever the household word that it always was. Let it be spoken without effect, without the ghost of a shadow on it.
Life means all that it ever meant.
It is the same as it ever was, there is absolutely unbroken continuity. All is well.
