I would absolutely call the mother and ask her what the hell she thought she was thinking leaving him at a mall without contacting you; there's no excuse, you drive a child somewhere, you are responsible for making sure that child gets home safely. In my mind there's no benefit of a doubt here, she was a jerk and needs to know that was not acceptable and you are angry, you didn't even expect her to bring him home, just have the compassion and brain cells to call you and then wait til you were there to make sure nothing bad happened to him.
First of all, if you have to consider calling your child's ex girlfriend's mother, or aren't comfortable leaving you child alone in public, he isn't old enough to date. Secondly, yes. That was immature of her to take off with her daughter and not stick around or offer a ride home.
Call her, and express why you were upset, calmly and rationally. Try not to be accusatory, it usually makes people defensive. Best of luck!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
