Compassion is a feeling, like empathy, but which often prompts one to look for ways to help the other person. One of the hallmarks of compassion is understanding the other person's pain (as in, "Yes, I'd feel pain were I in that situation too as I've been in a similar position before."). I try to remember to look for what is causing the person's pain and remember I'm trying to "help" and not necessarily just make the pain go away (for me or the other person).
