I remember one time my parents had a bid fight (verbally), hearing them swearing to each other hurts so much that I had to leave home. I just left home without telling them, I did not pick up their phone for many hours, at the end I phoned them and let them know that I don't want any more fighting and swearing at home. They stop the fightings after, at least they don't argue when I'm around.

Am I selfish that I don't them express their feelings?
