Can't remember - Getting into my fathers van and releasing the hand brake. Fortunatly my father managed to catch the vehicle as it slowley rolled away and get in and stop it before any harm came.
Remember, emulating my electrician father by sticking bare wire into a socket. 240 Volts in to a 1.5 Volt electric motor makes for spectacular preformance. I recall the black mark on the skirting board was there for a while.
Remember as screwed up sense of local geography, that eventuially led me to taking a "short cut" home that turned a three quater of a mile walk into a three mile hike!
