...after the fourth incredibly long pause in which I waited for someone to speak up in discussion:*
"There's something you need to know about me. Every morning, I practice twenty minutes of silent meditation. I also practice yoga 4-5 times a week. So not only can I outlast you in sitting here without saying a word; I can do it standing on one leg."
*To be fair, this class is not normally like this. But yesterday appeared to be the day that everybody figured that someone else would do the reading and talking. And for what it's worth, they laughed. But I think they'll come prepared next time.
