A friend of mine reminded me of a kind of joy that I hadn't considered yet; the kind that can't be seen (or photographed) or heard or touched or smelled. I gave a presentation yesterday afternoon and went home afterward feeling very powerful and pleased with myself (yeah, joyful). I thought that the presentation had gone well, I had informed the group to whom I presented about a topic of which they had little previous knowledge and (this is the best part) had sparked interest in them about a something that I find fascinating. The comment I made to my friend about it was something like, "There are not very many situations in which I feel the confidence of having more knowledge of something than my audience." But there's even more to it than that. The joy isn't so much in thinking that I know more than someone else (although I do admit that that is nice sometimes and it certainly gives me confidence when I'm presenting or teaching) but in sharing it with an interested and appreciative audience. And now that I think about it, there are some other occasions on which I feel that kind of joy. I feel it when I teach library instruction. I love the moment when I see the understanding dawn on someone's face. I also feel it in group exercise classes and used to feel it in dance classes, even when I'm not the instructor, the feeling that I'm good at something and am setting an example for others.
