I thought he was hurt but he stood up and walked away.
Why do you think he did that?
I think he just wanted to spare me any more ill feelings, even after I cursed him out.
Caring for others is often an important part of keeping up relationships with people close to you. Seeing his side of things helps you take the situation into perspective better.
But he's the one who ruined everything. My feelings are the ones that matter, not his. Why should I care about him at all.
Caring for others is a part of being a nice person and a compassionate human being. You need to look after other people better than you do.
