Child abuse, that makes me feel empathetic instantly, and search for a solution to alleviate their pain, if I can, even by defying my natural reluctance. Connection to childhood? Is it an Aspie trait?
Random things, I can get emotional over movies (some), novels, music. Music doesn't have to be 'sad'.
Unfairness, suffering, or unfair suffering, this last for sure makes me feel empathetic. When it happens to me, it makes me emotionally unstable, sad, angry, disappointed, apathetic.
My current quest for a romantic relationship imposes on me piles of bitterness to be triggered, I can assure you.
