Have you ever tried ice-skating? I wouldn't recommend it. There's the moment, looking out over the unpolluted ice when the possibilities seem endless. Your brain pictures you sailing unobstructed, with a grace normally reserved for soaring birds or swimming dolphins. Then your legs take over, you step out onto the rink and all thoughts of birds in flight are swiftly dispelled by the fact that one of your feet has gone off in a direction which they haven't found a compass point for yet, somewhere between N and NNE whilst your other foot is doing some intricate dance step which falls loosely under the category of a rumba. Swift, humiliating disaster ensues, closely followed by the desperation which comes from noticing that you have somehow ended up 25 yards away from the exit of the rink, facing the wrong way and a gossip of teenage girls is about to run you over. Now I’ve put that picture in your mind, perhaps my story of mine and my daughter’s first night together without mummy won’t seem so bad.
