A string of rude words, after stumbling about in the dark getting out of bed, and almost stepping on (which would almost certainly break) one of my vacuum take-off adaptors for my lab glassware set, and almost knocking a bottle of acetic anhydride off the shelf. That...would have A-caused serious burns and made my bedroom uninhabitable for quite a long time, and B-been an expensive, hard to replace fuck up, as AA is pretty hard to get hold of, seeing as its regulated due to its use in heroin manufacture.
