As a parent, you try to bring your children up in a safe positive environment, and keep them from adverse influences.
I get home yesterday and my 12 year old son, who has just started at the local High School, is in the bathroom drawing a pencil thin moustache, he was wearing his little sister's T-short AND had the sleeves rolled up, and had his old cycling knicks on from when he was 6 years old AND he had rolled the legs up on those. All I could get out of the kid was "Look at these guns - they are MASSIVE".
I might be leaping to a hugely unfair and incorrect conclusion, but I think my son may have Thor God of Thunder - he of puny thighs, as his PE teacher.
