I have a tummy bug. I know it's a tummy bug because it is combined with the awful chills, fever, faintness and all that other nasty stuff that comes with a tummy bug. I haven't been able to keep any food down all day and have been ill so violently it's pulled all my tummy muscles and makes it hard to walk. And yet at 4.41pm I am still at work. I just want to go to bed.
