Still learning to parent a teenager! His friends wanted to spend someone's birthday hanging out at the O2 centre. I'm a country girl - the idea of hanging out at a shopping centre all evening is totally alien to me! We're in Islington, where there's a serious knife crime issue. I realise O2 is a different scene, but I can't help thinking unsupervised teenagers in a mall for 2 hours could go horribly wrong?
