I don't know why I do this so much. But I find myself always throwing in some trendy brand-name item. I do it at least once every other chapter. I throw in things like: I-pad, Wii, Starbucks, facebook, etc... I always strive to write something I will be proud of, even twenty years later. Is it silly to worry about these things? Mind you, the items actually do serve the story well. For example: in one scene, I couldn't just say they were playing video games, but instead opted to say, "Mortal Kombat for Wii". It gave context to two goofy adults in their living room flicking their wrists about, and then one dropping to his knees in defeat when "Finish him" comes thundering through the speakers. But this is always something I'm worried about. Any thoughts?
