Lauren -- crazy people don't have to justify themselves to other crazy people. :) And I use random odd phrasing all the time. I can't think of an example right now but I know there's one phrase I always use and I know that this particular character says it once in this one book...oh! "That's as may be." It creeps into my phrasing at odd times. I'm sure there are others, but that's the one I can think of right now.
