I've just had to explain this to my 6 year old DD after she must have miss interpreted what the principal said at the Harmony day assembly. DD came home saying people shouldn't have dark skin in this country and should go to there country then asked why they had dark skin. My answer was that people come from all different places that have people talk different, look different and sound different but they all take after their mum and dad. Followed on about coloured hair and eyes which she seemed happy with. Also included that anyone of any shape, colour and size can live in this country which she was happy with.
