I love this poem...

LIFE GOES ON

If I should go before the rest of you,
Break not a flower,
Nor inscribe a stone.
Nor, when I am gone,
Speak in a Sunday voice -
But be the usual selves
That I have known

Weep if you must;
Parting is hell.
But life goes on
So... sing as well.

Joyce Grenfell (1910 - 1979)

(Every version I looked at had different punctuation, some had none!)
