I remember being 23yrs old and my son (aged 5yrs at the time )asked me if I remembered the Dinosaurs!!! now that made me feel old, but it was so funny..lol:-)
Travelling accross London with my four year old son on a packed tube train, I thought about my working past in the capitol and thought out loud "Can't believe I used to do this every day" my son said "Dad did they have trains when you were little?"
