I know! I am such an idiot. I cannot believe I left my keys at work. I have no idea where they turned up - I'm just damned thankful they did. They must have fallen out my bag... when? I have no goddamned clue. Oh well, chalk it up to experience, at least it's midly amusing on reflection and I can make people feel pity me massively, Mary Sue style, when I tell them what an idiot I am...
