So much cheating! Good grief, I hate cheaters, so ch. 5 especially pissed me off. There's nothing like a cheater that keeps saying I'll never do it again, and I'm so sorry, then turns right back around and does the same thing over and over. Then to have such stupid reasons for doing it (not that there's an especially good reason for cheating).
