Angry Rant of an Elder Sister

You speak such idiocy to such an impressionable mind, he knows nothing about what you're spewing but he's a sponge and soaks up every last word. He then repeats it and pesters on about it a dozen times in just thirty minutes, imagine how many times in one day. All you can do is sit back and watch? You're his mother for peat sake!  Stop your idiotic boyfriend from poisoning your son's mind. I'm so sick and tired of you getting angry with me when I get annoyed with you because you can't help your own son. And when I try to re-shape his mind, to try to help him, he doesn't like it. He doesn't like to hear the words no, or not right now. He throws a tantrum and then you get angry with me for 'antagonizing him'. Seriously?! Really?! Open your eyes you blind woman. I'm trying to help him, yes I get he's got Autism and doesn't understand what he says or does. You're supposed to coach him, teach him, help him to be better, to try. Not just sit there and let his mind become demented due to some moron's lack of intelligence. Put on your big girl panties, you parenting pants and actually parent around here. I'm so sick of doing it and then getting yelled at for caring. Will I stop? Can I quit? Of course not! If I did, I could only imagine what would happen. To him, to my other brother. I'm only nineteen and yet I have better parenting skills and you have three kids! How on God's green earth does that work?! Please explain that to me.
