Lash out and hurt a innocent person, when it's really someone elses fault. Like in love, A lover get's treated poorly because there spouse has been broken hearted repetedly. So the broken hearted, treat the new innocent lover badly Or as simple as a adult suffering money issues, and they take it out on there kid.... By dealing with a stressed out mother at home, who yells, and crys, and is destructive. Would this be almost selfish? In a odd way..?
I think alot of times its a comfort thing. Maybe if I had a bad day at work I will bitch at home because I am so comfortable with the people at home.
I think is because people to not know how to channel their frustration and feelings. They need a healthy outlet for feelings and stress and they do not always have it. Also I expect holding feelings inside causes them to come out at a later time. It is kind of sad.
