My husband and I were friends for years before we started dating, but when we got serious, I bought him Matilda and Harriet the Spy, so that he could get to know what I’d been like as a kid. (Though tbf I was only 13 when we met, so it wasn’t like he didn’t already have an inkling!)
I borrowed Wreck the Halls from the library based solely on the cover art – it looked like a hallmark Christmas movie in book form, which is what I need right now. Two pages in, I discovered that the two main characters are the offspring of famous musicians, and their names are Melody and Beat. Vom. Immediately returned it.
