When I accidentally delete text on my document (Windows Word), I can easily recover the deleted part with maybe one or two clicks. In case the document got already deleted from the bin, it is still possible to recover the file with simple software/programms. So I do not see the problem.
Maybe she's got problems with her computers, so why not write the lyrics down on a sheet of paper?
So, I don't really believe her story about having deleted the lyrics once again
But funny story xD
