It doesn't surprise me, unfortunately. My BILs car was damaged by a boy little older than 7, while he was trying to play chicken with oncoming traffic 
, parents no-where to be seen. BIL asked where he lived, so he could take him home, presuming he had ridden off and his mum/dad didn't know where he was, he was swore at.
He followed him home about three blocks and one motorway away , to tell his mum what had happened, still presuming she did not know where he was/what he was doing. Mum apparently told him "I have 7 fucking kids and I'm a single mum, how the fuck am I meant to watch all 7 of them all the time?" . I feel very sad for her children.
