Oh yes, quite often, and with lots of people, too. All my relatives find it very hard to agree with me on anything, for instance. It's amusing being the "black sheep", all the time. And there was this chemistry teacher I had, from 8th grade onward. She was, indeed, literally crazy. And I mean it, in the real sense of the word. My problem with her, wasn't that she wasn't teaching us anything whatsoever concerning the subject, whilst discussing the weather and what not, because, not to offend the "scientific crowd" here, but I couldn't give less of a toss about anything other than the theatre and maybe English. The problem I had with her, was that, as oblivious as I might have been in this particular subject, I still knew more than she did about it, and it was quite hard to try and not to argue with her all the time.
