I'm hip, yeah? I occasionally wear skinny jeans and an over-sized coat. I can be cool and down with the kids (ignoring the fact that I am fast approaching my mid-30s). So when we were invited to the opening of Neverended, an exhibition of London's graffiti and street art in uber-hipster Shoreditch this week I wasn't going to let a little thing like my lack of street cred get in the way.
