Yesterday I had my Life On Mars moment!
I took my elderly parents to see the tiny old terraced cottage where we lived in the Nineteen Fifties. They had not visited the area for many years. I was 4 to 5 years old at the time I lived there. As we sat parked outside in the car - a little boy of about that age appeared at the door and waved! We waved back - and drove off. Or perhaps, rather, it was his Life On Mars moment.
