Where do you guys usually buy your books? Like do you buy them used at thrift stores or brand-new like at books-a-million or Barnes and noble studs stuff like that. Almost every book I own I got at thrift stores (except for the ones I've won at DOGO)
You could ask the troll "are you my friend" and the first troll will to the truth and then the second one would lie so you can keep track of each troll you ask and find out which one is your friend? Right...?
