(Of course, a really bad book can make a person happy and sad for very different reasons, most of which are aptly described in German, but that's another story.)
The thing is that I've never really been one to cry at a book. I've read many books that I loved, in which I found myself completely engrossed—but crying, actually being physically moved to tears? It's not really my thing. In my recollection, only two books have made me cry, and probably not the ones you'd think. (Of course, I also don't scare very easily, so maybe I'm the problem.)
So, having established that my tear ducts are, in fact, filled with cement, I'm terribly curious to hear from others. Are you inclined to cry with books (comics/movies/whatever)? If so, which ones affected you the most? Do you prefer crying over what's very personal to you, or will a more general tale of woe move you just as much? Leave your wisdom in the comments! I'd love to hear your thoughts.
