I Can't Believe I Did This

So yeah, I kind of got lost in a bookstore last weekend and ended up buying three copies of the same book. You know how it is, I was trying to find that little section near the back where they keep all the self-help stuff on relationships or something like that, but instead, I stumbled into this huge sale area with these big stacks of books everywhere. And there was a copy of 'Finding Yourself in 365 Days' at every turn! At first, I thought it was just because the book was popular, but then I realized I must have passed by the same pile three times before actually grabbing one to read. So I did, and then another for my friend who's always talking about how she needs some good relationship advice. And then, well, let's be honest, I was too embarrassed and already out of money to go back and return it or even put them all down. So yeah, now I have three copies of this book that look exactly the same and I'm pretty sure my roommates think I've just completely lost it. Maybe I should just donate two copies somewhere... but seriously, how did that happen? And why do I still keep them around? I mean, they were on sale, so maybe it's not such a big deal? But honestly, there's something kind of embarrassing about having three identical books sitting next to each other in my apartment. Who does that?
