Have you ever bought a book, started reading it and then realised you have already read it? If so, how far did you get? (Can you tell this happened to me for the first time ever this week!?!)
And–did you keep reading??
This hasn't really happened to me before but I nearly ended up buying a book from a bookstore once that I already owned and had read! It had a different cover and was in the bargain section so thought it was a really good buy and was sooo close to going up to the counter and buying it. But then something obviously clicked in my head and I realised that I had read it a year or so before and was saved from wasting money! I think I bought another book then that I luckily didn't own and hadn't read before!
