The one with the head = desk

I have just managed to get my whole foot into my mouth, by accusing the head PA of losing papers, god!! And where did the papers turn up in my office on top of my filing, god I am such a hopeless PA sometimes. I didn't know what CEA stood for (being a weirdo medical term and all) it means Clinical Education Awards and somehow CEA didn't click with the name on the folder, thank god head PA has forgiven me for being such an idiot. And it is only 9.45am, I have a long day ahead of me, I think I will go and apologise some more to head PA.
