I was once in the background of a news piece, I didn't know I was being filmed.
I was watching Only connect recently and thought, 'he looks familiar', it was my cousin.
Half of my degree was Deaf Studies so I often see interpreters I know or used to know.
Oh and I saw an old uni friend in an episode of 'New Tricks'.
I saw an old work colleague on TV, something to do with holidays and he said, "I've been coming to Cornwall for 20 years I won't go anywhere else".
I remember when I worked with him and his wife wanted to go away to Spain on holiday, he didn't want to go because, "I've been abroad once, they say they have English food, but they don't, it's different"
It summed up hi attitude to life very well.
