I've always thought I wanted to learn the constellations and be able to name them as I look up at the night sky. Then my kids came along, and we've been teaching them about these things. We even took them to a little stargazing education class last Friday night, and I learned something about myself: I'm just not interested in that stuff. Don't get me wrong; I'm glad astronomy is a part of human knowledge, and I know it's potentially interesting. But I have no real interest in it myself, try though I might. Perhaps that's in part because the part of me that, geekily, might wish to say to others, "Hey, I know something about this" and then demonstrate it has been beaten down through years of observing/moderating Internet comments. I dunno. But to me, a collection of white points in the night sky doesn't add up to much. I'd rather call it "star cluster R-532" or something. If that's boring, at least it's fitting.
What about you? What hobbies or areas of knowledge just don't capture your fancy? Discuss.
