You know the Internet has taken over your brain when you find yourself typoing ‘relolcation’. Or ‘allolcation’.

Last month I went to Borders, in Cambridge town centre, and bought a pile of paperbacks.

This evening I was sitting on my sofa reading one of them; I turned a page and found a receipt stuck between the pages. A receipt for the book I was holding – from WH Smith, in Cambridge town centre, dated February of this year.

What happened there then? Best explanation I can think of is that somebody bought it from Smiths and then managed to leave it behind somewhere in Borders – perhaps in the café – and when the Borders staff came to clear up they saw a pristine paperback, assumed it was part of their stock, and shelved it. How strange. I wonder if I ought to notify somebody.
