Epitaph for a Sad Gentleman

HE has been tristful to the last,
He has been pensive unto death;
Now he will never breathe again
Who drew a sigh with every breath.
Do not presume to weep for him
Who wept as you will never weep
And let him lie unmourned who lies
Consummately in mournful sleep.
No sweet celestial smile shall twist
Lips that have been demure so long;
He will walk plaintively in bliss
And praise the Lord with a sad song.
