Thursday 6 November 2008: Of the first kind
When I was a small boy and lived in a Welsh valley, I used to see UFOs fairly regularly.
I can remember my friends and I playing on the village crossroads one dark winter evening (because that's what you do in a Welsh village of a dark winter evening), when a very well lit but indefinably shaped craft flew very low and very slowly over our heads. It made a noise, but certainly not that of an aeroplane.
I used to see ghosts fairly regularly back then, too. Never seen either since.
