Well, I wasn't going to name the books I picked out for the trip because I didn't want anyone to feel bad that I didn't pick theirs first (OMG that is so ENFP isn't it?). But this story was too good to pass up, so thank you for all the great suggestions and I have this list saved for future reference...
OK here's my story:
I went to the bookstore to get 'One Hundred Years of Solitude'. "oh yes, says the lady at the reference counter, an award winning classic! We use this one for our advanced studies class."
So then I ask for 'One for the money' by Janet Evanovich. Her face turns all quizzical looking... "Is that for a different person?" I really didn't want to explain, I just said, 'yes'.
