Save

"Where has it gone?"
"Did you press save?"
"Of course I pressed save. But now it's gone."
He hadn't pressed save.
"How much have you lost?"
"A full afternoon's work."
He'd procrastinated so much that the full afternoon's work in question was the grand total of 278 words.
"I'm going to have to do it again now. It'll be a long night."
It wouldn't be.
He left at his usual time.
