“ONE SENIOR for How to Train Your Dragon, please.” I uttered those words the other day when going to the movies with a like-minded friend. Yes, you can be over 60 (or any age, really) and love kid stuff. I feel more and more ready to stop caring about being cool and go and see/read/listen to the things I really like, be they ever so juvenile. (The dragon, by the way, is toothsome.)
