I made the mistake, after shabbos was over, of trying to clean up my email and delete outdated stuff...
This is the undoable task.
Reminds me of the lines from the poem "The Walrus and the Carpenter":
"If seven maids
with seven mops
swept for half a year,
Do you think", the walrus said
"That they could get it clear?"
"I doubt it," said the carpenter,
And shed a bitter tear.
And now, refreshed by shabbat, I will get a good night's sleep and prepare to SING tomorrow night.
