Scanning, you certainly can tell the tale, but you must keep a check on what you've written previously if you don't want people calling you a liar..
As 'ali_alic' says, you were a manager on a previous posting; if that's the case why don't you manage instead of having to whinge to us. I hope you haven't been demoted in the last couple of weeks!
If it is the case that you are the manager, I trust you don't type up your managerial reports in the same way as you write your postings on this site.
Use a few paragraphs to break the story up. Don't serve your story up in one great lump. If it's more than five or six lines long, paragraphs are a must to make the posting readable.
Getting back to your 'colleague', how comes he whistles war songs when he wouldn't have been born until well after the war finished? Now, Beatles songs I could understand!
But this leads on to another puzzle, I work in an open plan office, and there's no way that anyone would dare to whistle in it. It would be the height of rudeness when others are trying to work. When I think of it, I cannot recollect anyone ever whistling in the office, and in fact hardly anyone whistles at all these days.
Looking forward to your next entry, they cheer me up!
