What did your mother always tell you and do you apply that in your adult life?
My mother always said 'two wrongs don't make a right'. To me, that means my actions stand alone. It doesn't matter what someone else did that was worse or whether they did something to provoke me, I am responsible for myself.
"It's at times like this, when I'm about to be thrown off an alien space ship six light-years from the smoking remains of the Earth, that I wish I'd listened to what my mother tried to tell me when I was young," said Arthur. "Why, what did she say?" asked Ford. "I don't know, I didn't listen."
She was a step Mom that wasn't into the scene. Step dad adopted me. Can't remember any thing that she would say like that. Her thing was to accuse me of something then switch me on the legs as her punishment.
