I'm one of those people who would do just about anything to get out of an argument, so much so that I sometimes have to resort to never being wrong about anything in the first place. If you're like me you will have a contingency for everything, and if you're not like me, just take whatever I say on faith until you change.
These days, on an almost daily basis, I find myself needing to apologize to someone. Sometimes I even need to apologize sincerely. When that happens, I make a wrongcard. Then I ask myself 'what have I got to apologize for?' and, instead of sending it, I eat a muffin. It's a pretty good system really.
