I've never booked myself off sick, seems like unnecessary paperwork, my boss won't know how to approve it because Americans aren't allowed to be sick (it's almost that bad). I just come and go, I like to think of myself as more of a tide than an employee.
Other than a horrid spasmy hypersensitive throat and the occasional outburst of residual nasal ectoplasm, things seemed to be settling down.
I am feeling odd though. I'm tidying my office. And before that I sorted all my pension statements into the three necessary piles as a prelude to handing them to a grown-up to make sense of. This isn't me. I never tidy my office. And I certainly never file paperwork. I have been replaced.
