That happened to me before and everyone stared and I just looked at them and thought, don't hate because I bought the watermelon. And then I thought, I wonder if that made me broke, how much did it cost?
I do this more often than I'd like to admit. I count wondering if I really want to read more, then I start reading more, get hooked, and I end up not being able to put the book down until I get the answers I want. Only for school books tho lol
