I completely agree and this is why I took the step to tell the principle. She called the mother and I hoped that she would think to herself and ask the right questions - "like why did you do this, has this ever happened to you etc". When the mom came to my house I didn't want to emphasize this was malicious because it's possible it may have been innocent.

Then things turned sour and we had the big blow up and I realized they were twisting it around and blaming us for over reacting. I wasn't about to sweep it under the carpet because this would teach my daughter, that something like this 'isn't important' and we need to be quiet because we're afraid to ruffle feathers.

I wanted the principal to call the mom, just in case there is something going on at home. Her father is a doctor. One day in class, the kids were talking about misbehaving siblings and this girl said her older sister was throwing a tantrum about going to piano lessons and she said the dad spanks her on the butt. Her brother who's 6 has some serious behavior problems. Once at a track and field event the oldest girl had a plastic foot boot(she had a broken bone) and the boy stomped on her foot with his heel twice. A short time later, he spit directly in the girls face when I was talking to her mom - this is when things were peaceful.

When we had the last confrontation, the father looked furious and I got the sense, he felt like I ruined his peaceful family life. I suspect you could be right but I can't do anything about it. Things are still going well - all concerned are behaving well and leaving each other alone.
