You're in the bookstore and you see the book and you say to yourself, "Self, you should read that book" but it's hardcover and you can't afford it or you already have a trillion other books waiting to be read because you promised them they were next so the only thing you can think to do is to log the ones that look interesting in the hope that, someday, the world will slow down -- and you can sit in your reading chair with Fido by your side, and learn something new.
