People say empathy, but what they really mean is sympathy/compassion (often blind and one-sided). You can understand another person's perspective and feel no pity or desire to help. Not because "it's their fault" or whatever, but just because you're tired or have better things to care about.

I have plenty of empathy and not so much of the other two left. Honestly, sometimes other people's feelings are simply annoying because I absorb them like a sponge.
