Crikey, I know just how you feel. I had encephalitis in my early 20s, and, well, to cut a long story short: aphasia, dysphasia, and the shakes when I'm tired. When I first went back to work After, it happened a lot - most memorably when I asked my boss to lend me her clitoris. God knows what misfired there, but she, without blinking or commenting, handed me her stapler. I would probably never have known I'd said something wrong if the rest of the room hadn't erupted with laughter...
