An elderly lady is talking to an elderly gentleman acquaintance, whom she has met by chance. They are discussing the cheap Christmas decorations she has just bought:
"And see, you get three for 99p and my grand-daughter has a little Christmas tree in her bedroom and so I got her three packets with different designs. Because at 99p that works out at about 33p each, which is a bargain, isn't it? So I got her three of those and then I went to the pet shop and bought a frozen rat for my snake. Oh, I've had him about fifteen years. I didn't know snakes could live that long! He's only about six feet long; I share him with my downstairs neighbour after he escaped and she found him in her washing machine."
