So my stepmother is currently yelling at my brother and telling him to shut up (screaming so loud that she woke my son up) and threatening to smash his phone to pieces.. All because he didn't "correctly" clean the dog's water bowl outside this morning, even though my dad saw him... a little dramatic? She is such a psycho, she put me through hell as a child. She is just filled with so much hate. I would never speak to my son in such a manner, and if I ever had stepchildren they would be treated just as well as my children I gave birth to. That's how it's supposed to be! You sign up to play the role when you marry someone with kids.
