That Strange Feeling of Empathy

I was watching The Matrix Revolutions for the first time in a few years (I'll try not to give away any spoilers), and there was a scene during which Neo was sad about someone else, and I actually felt really sad for him and not for the someone else, sadness that I don't remember feeling last time I watched the movie.  Feeling sad for someone else because they are feeling sad about something else is really complicated, but my brain learned how to do so (at lest for a fictional character).  This makes me hopeful that my brain development is headed (get it? my brain is headed? I think that's funny) in a good direction.
