Ds 6 came home upset as a girl had hit him.He said he felt like hitting her back.I explained that in no circumstances should he hit a girl,ever.Ds said "well who protects the boys,why should boys get hit" Noone should hit anyone was my reply.I didn't want to say that boys are stronger than girls or any rubbish like that but what do you think is the best way to explain if it comes up again?
