The only one who owes me money is from a situation that has faded in memory. No, I'm not bitter. I don't want to "out" him, because the situation would have most likely resolved itself if I hadn't misplaced a document.
This is a "shit happens" business. Sometimes you get obviously and blatantly ripped off, but for the most part..."shit happens" strikes and there isn't anything either party can do about it.
I focus more on the people who have gone out of their way to do things to help me - things that they do professionally - and have done it for me just as a favor.
I'm having a "the glass is half full" kind of day, apparently.
