Clueless!
I had received an e-mail from an account manager whom I loathed for her inability to do her job correctly, even at the most simple level. After receiving this ridiculous e-mail from her, I wanted to send it to a peer of mine whom I had vented to to witness firsthand just how bad she really was. I flamed intensely on the forward, and then sent it off -- only to realize that I had REPLIED to the e-mail, not forwarded it.
Noticing that the acct mgr was busy with an artist, I raced down one floor to her office and leapt into her e-mail app. Inbox-delete. Deleted Mail-delete. Repeat, repeat...
As I nervously double and triple-checked my efforts, she appeared. "What are you doing?" she asked. "Just testing a beta of a site on Windows. You were upstairs so I knew your computer was available."
She didn't have a clue (like usual). I nearly had a heart-attack and a pink slip to match.
