I got a call yesterday from our daughter's school, and had to pick her up my 11 year old following an "incident" at lunch. She was waiting in line behind an older girl (13-14) who was singing inappropriate, sexualized lyrics and generally behaving badly, when the older girl turned and grabbed her crotch, then started walking away. After a moment, she returned, said "Oh sorry, I thought you were someone else" and left again. Obviously, this upset her badly, and she told the principal, who then called me in. We were told that it didn't appear to be targeted as the girls didn't really know each other, and that the perpetrator had no history of this sort of thing (although some of the kids appear to think differently, and one teacher confided that the girl had a "unique" and difficult personality when she was in her class). At this point, we have not pursued charges, and the school's punishment is pending (it looks like a suspension, which by the timing of spring break, may be only for 1 day). We did make an inquiry and spoke to a police officer who informed us that filing a police report would lead to an arrest, and that we have an incident number to refer to should we choose to go that route. My daughter, while shook up, is a strong and resilient girl, and I'm sure she'll be fine. My question is, keeping in mind the ages of both girls, what do you think is an appropriate response?
