FULL RANT MODE (accompanied with tears of pure frustration)
What are the chances that the receptionist (on her lunch hour) would freeze, crash, and totally fubar a company PC (that she has no business using) that handles, amongst other things, the dedicated email client for receiving invoices, the end-of-year financial spreadsheets that should be updated daily, and ..... I can't go on ....
Yes, I hear you say "Why wasn't the PC pass-worded or restricted to prevent casual users from .... well, using it? Well, my boss hates passwords and refuses to have them on PC's he uses (I'm not making this up), and his sister is allowed free run of the company, including using company PC's for her personal use ....
I'm almost beyond words, having spent the afternoon fending off demands for invoices, spreadsheets, etc., as I have had to fit PC repair into an already full day. And of course the stupid b***h is lying as to what she was doing before the freeze, and what she did to cause the crash - so I'm working blind trying to preserve the morning's data and NOT do a restore to a previous day.
So, during this wonderful afternoon, my boss drops in to say I'll be getting an email with a LOT of attachments - he has decided to acquire another (failed) business and wants me to go over 7 years of tax returns & financials .... on top of everything else I'm dealing with.
I'm having chest pains, stomach pains, head pains, and am mad as hell! I'm seriously considering walking out of this hell-hole and bagging groceries. "Paper or plastic?"

Going home now to play with the cats .....
