When I was writing my book, I put in a scene where the main character, Jeff, becomes a fan of Dave Matthews Band much like I did which is apt considering my book is based on true events. From the moment I wrote it until today, it is such an awkward scene and I wish I would've taken it out.
I always find it awkward when creators try to shoehorn in what they like. I'm guilty of doing it but you have to admit, it can be pretty awkward.
