Sorry, but I have a now 18 year old who was severely ADHD when he was younger. The behavior you describe has absolutely nothing to do with ADHD. Has everything to do with your sister not enforcing the play rule for all the kids to pick up before they leave and for there to be an inspection before they walk out the front door. Most kids left on their own without guidance would choose not to help clean up. That is just natural.

As for calling the parents, try it if you think it will help. However, as witnessed by numerous threads on the CB where parents are infuriated because another parent called about their children's behavior and how their child would never do such a thing, it will probably be a futile effort.
I would just either end the friendship or do a bit more supervising to enforce strict rules in your household.
