I am staying over in Tor's grand old English farm set in hilly terrain. The sun is shining and it is a beautiful summer's day. A school party of primary kids are descending the hill. We hear a big crash from the courtyard and go to investigate. The snow has melted and slid off the roof flooding the yard. Bulbous icicles hang from the trees. You'll have to go round the back, I tell them, its too dangerous here.
