Exactly! Your theory definitely holds weight. It's a good explanation although I still can't stand people like this. Do we excuse such behavior because of someones upbringing? I mean, my mom physically beat me but I would never think to be excused if I did the same thing to someone else. I think people like this lady, are born and bred to not have a conscience! LOL!
I've been used and abused before by other moms. I had to quit carpooling with all of them because they took advantage and never wanted to help out in return.
