Neighbour is a lone father to two kids, both primary school age roughly between 9-11
He goes out probably 3-4 evenings a week and leaves them alone sometimes till 10.30-11pm sometimes till 2-3am
He also goes out early sometimes around 5.30am with golf clubs, they are also left alone a lot though day when he goes out and seem to be taking themselves off and home to holiday clubs alone too
Is this a concern or at there ages is it ok ?
