Not your circus not your monkey. I wouldn’t be so quick to be diagnosing other peoples kids, but if you’re concerned about her behaviors, I think that would merit a (friendly, civil) conversation with her grownups.
I would also say to steer clear of picking your kids friends for them (and that includes excluding people from being their friends). Thats a a parents doomsday weapon. You save that for kids who really rub you the wrong way. That breeds resentment. If you have concerns about their friends and who they associate with, you need to progress to that tool after weighing other options…most importantly, starting with having a mature and respectful dialogue with your kid about the types of people they associate with. They are at the right age that you can and should be having serious grownup conversations with them and connecting with them as if they are more of an adult and less of a kid. Give them the respect they deserve as long as it is reciprocated.
