Wake Up Crying

I was looking in my library's for sale section, and found a nice made-from-scratch empty notebook for just twenty five cents. I picked it up and thumbed through it to see if it had been used at all, and I found one page in the back that had been written on. It's incredibly interesting to me - to know that someone may have written it, forgotten about it and submitted it for sale; or maybe they knew it was there and sold it anyway?
