Venting for the day, computer problem

[Tindomul]

Tell me why my Wife stayed up all night working on a power point presentation for bio class on symbiosis, and saved the presentation multiple times including twice in front of me. And then she accidentally closed the power point thinking she was closing something else, and pufff, no more power point. We looked everywhere. Documents, desktop, recent files, power point program itself. We tried searching for it under the name she had saved it under. She went to school crying and shaking and we had to pay a cab tons of money so she could get the luxury of sitting down and attempt to quickly remake the power point. She was going to be early, she had a beautiful presentation, and she did everything right. And still, the computer royally screwed her.

Any comp experts out there have any clue?
