Sylvia was slightly concerned about a mini-drama that had occurred (in the never-ending saga of dramas that make middle school so much fun), and people asking her about it the next school day. She wasn't sure how to deflect the questions effectively.
After convincing her that "it's none of your business" wasn't going to cut it, and perhaps trying, "I don't want to talk about it," she still wasn't sure that they would leave it at that. So I suggested changing the subject, and making the conversation all about the other person...in a good way. Compliment the questioner's shirt or shoes, or just ask about their weekend. I told her that people usually love to talk about themselves, and it's usually the quickest and easiest way to deflect.
That's the one idea she seemed to think just might work. In the end, no one asked her, but I think she'll still end up using the method at some point.
I don't know if anyone ever actually taught me that, but it has come in handy for me quite often!
