In a very belated attempt to teach myself the value of money, I have embarked on one of those régimes where I am only allowed to spend a certain amount each day.
This has completely transformed my outlook on life, as can readily be apprehended from the following conversation.
ME: Guess how much a banana costs?
THE LOVELY MR BC: (playing unspeakably violent computer game) Arggghhhh.... unnnfff... grrrr... arrrggghhhh... Yes! That's what you get for messing with the J-Man!
ME: No, seriously, guess how much a banana costs?
Mr BC: Erm...thirty pence?
ME: I got one for eighteen pence!
Mr BC: Well done.
ME: From Marks and Spencers, as well! You can probably get them even cheaper in Tesco's! Ooh, and guess what?
Mr BC: What?
ME: I bought two salads - it was buy one get the second one half price. Which means I saved a pound! And it means I've already got my lunch for tomorrow. See how I've learned to plan ahead! Ooh, and guess what else?
Mr BC: What else?
ME: I was buying these yoghurts from Starbucks, right, with seeds in them, and they were two pounds each. Two pounds! For a yoghurt!
Mr BC: Yes, well, two pounds is a ridiculous price for a yoghurt.
ME: Well, they did have seeds in them. But then I discovered that if I bought seeds separately, and a packet of four yoghurts, I could save three...no, four... no, wait, SIX pounds!
Mr BC: Mm. Very good.
(A companionable silence ensues, during which time several Eastern European gangsters are violently dispatched)
ME: Is Time Team on yet?
