I'm currently watching a classic episode of "Coronation Street".
As I turned on my TV, I saw good old Emily Bishop - played by actress Eileen Derbyshire.
I was immediately put in mind of an occasion when I had lunch with Eileen in the BBC canteen at Manchester.
She was sitting opposite me at the table and I was eating a cheese salad.
As I attempted to cut a very small tomato with a not very sharp knife, the knife slipped and propelled the tomato away from me towards Eileen, passing straight through a mound of grated cheese as it made its way towards her.
She was good enough to return my tomato before gracefully proceeding to flick a significant amount of cheese shrapnel from the front of her jacket.
She saw the funny side: she's altogether more of a character than Emily ever was, I can tell you!
