Apparently this kid is 'super rich'& always flashing cash.. this time my DS (year 7) helped him in a lesson & he gave him £20 in return. My son took it, delighted! We have explained to him this is not right & told him to return it, which he now understands & will do. But should I alert the school?? Should point out this is a state school, admittedly in a pretty wealthy area.. but it's worrying 12 year olds are taking that much cash into school right?
