Y Lee: I don't think a 13 year old being scared of getting punished, no matter what the punishment is, means that I need to "change my horrid ways". I was terrified of getting spanked as a kid, and the spankings I got barely qualify as such based on conversations I've had and stories I've read over the years. As an older teen, I was just as terrified of getting yelled at or grounded.
From Carrie: "Once you've seen, you can't unsee"--or to paraphrase, once you've heard, you can't unhear.
Having heard, I'm going to knock under pretense of telling the boys goodnight, and ask Oliver and Oscar if they have anything to tell me. Hopefully, at that point, Oliver can come clean, and unless he's committed a capital crime, I can surprise him with a discussion rather than a whuppin'. If he fails to do so, I will apologize, point out that I wasn't eavesdropping, but I couldn't help but overhear the boys' conversation. And ask my question again--hopefully with the result I'd hoped for the first time I asked. If I have to pull teeth, probably a whuppin' is going to be the result for Oliver. Oscar isn't really involved--when I find out, he'd just found out, and again, unless this was a capital crime, I wouldn't really expect him to rat out his brother.
