I'm in the final editing stages of my final essay for my degree in English Literature. The arguments are made and referenced, the threads pulled as tight as I can manage. There's just a little tweaking for an extra mark or two to send me over the edge. But then, like a bursting bubble, the clarity's gone and I stare blankly at the alphabet soup on the screen.
Time for a run round the block, I think, or some vigorous housework, in the hope the fog will clear.
Just one more hour and then press 'send'.
Edit to say: it's sent now. What a relief!
