I agree with Hashi, it depends. My sister and I have different ideas of what discipline should be. What I think is abusive, she does not. I'm not sure in a court of law it would be considered abusive. She knows I don't agree with her methods. I think her kids know I don't approve either. I know my children know. I keep my eyes and ears open to make sure it isn't worse, but I think it is sometimes hard to know what goes on behind closed doors. Not always, sometimes. I also know that she has physically kicked her husband before, but I don't know if it has ever been more then that or if that was a one time incident. I would have to know for certain that that is what is happening in their house.
