I'm afraid that's whats happening to me at work! I work for a lawyer, and he keeps catching things that I've forgotten to do, but I swear I did. I can even "remember" doing things, that upon evidence, have NOT been done, or vice versa. I've done things, but do not remember doing them, or so it seems. Like saving a document after changes have been made, then emailing it to god and everybody, only to have my boss print the emailed doc in my face and ask me why did I send the incorrect do, didn't I make these changes? I absolutely don't know what happened. And its not the first time! I am so scared I'm not going to be able to hold this job for another year, let alone, ten (which was my hope).
