This is an extention of my other 'need to share' thread in healthy parenting. We've been having off and on problems with the family down the street, ever since I told the school their daughter touched my daughter inappropriately at school.
The last month the mother has stuck my oldest the middle finger as my girls are waiting for the bus in the morning. My youngest wasn't looking at the time. My youngest in on a different bus in the afternoon, so she's let off across the street from our house. She's only 9 and the mother was driving by and boldly stuck her the middle finger at 3:10. To me this is disgraceful.
I called my husband and he said to make a report with the police, since this seems to be an on-going problem. I called and they came right away and said they would warn her. I feel mad and wonder, when it will ever end. I'm not the type to fight dirty and I'm usually a good problem solver but I can't think straight or deal with an unreasonable person.

What would you do?
