Oooooooh, i am so very sorry you had to be the object of these people's insecurities..
it's a shame when mother teaches daughters to be so critical.
I imagine the mother has a dreadful, loveless marriage to act like that and she's teaching her daughters to be just like her.

Hold your head up high and be thankful that you have more integrity than that trash!
had it been anyone else, they probably would not have acted as demure as yourself.. they probably would be sitting in jail with a battery charge hanging over their heads!

be thankful you were taught right.
