This happened a while ago, but Ive only just stopped laughing enough to write it down.
The other day, two ladies of my acquaintance were out in the car. I suppose it does no harm to reveal that they are in fact my mother in-law and sister in-law (both absolutely delightful people). They drove past a house which was evidently undergoing a good deal of building work, and outside of which was situated a 'portaloo'.
"Oh" says Mum, "those people must really like Doctor Who! Look, they've got a Tardis in their garden!"
I do hope she never has occasion to use one of the few remaining police telephone boxes to be found in our green and pleasant land.
