I take a couple days to read the first Harry Potter book. I just read slowly, at an irl conversation speed, to make it seem more real. On the other hand, that also means I get to spend more time enjoying a book than all you speed readers.
That said, I haven't read a book in about 2 years, because I can't be bothered to put in the time and effort it takes to start a book (let alone finish one). In fact, I'm pretty sure the last book I read was the third Hunger Games book, which I didn't finish, on account of it boring me to tears. In the end, I prefer games over reading. In fact, I'll just go ahead and put reading towards the bottom of the list of things I like to do.
