[modest shrug] "It's all down to experience, son. I too as a young clamper paid the ultimate price for being impetuous. I have seen so many cases overturned in court on a technicality. Now, get the camping chairs and the flask of tea ready, it could be a long wait, but the little bastard will have to touch the yellow line at some stage!"
