To be fair the word contact is kinda sus. I had CPS “contact” when I broke my arm in kindergarten.
I was pushed off the play ground by another kid while at school. My parents were both at work. I had a lot of bruises they also didn’t like. I remember getting questioned about it at the hospital for what felt like forever. They kept pointing out scrapes and bruises and asking how that happened. I had no clue and kept saying from playing.
That sounds like the bare minimum to qualify as contact.
My only point was I never listened to a boom box outside.
