I worry about mine in my fiction, that it's fake-sounding and not realistic. And then I listen to a popular show like ER last night, and my gosh - that's fakey dialogue! (For those of you who watch it, I'm thinking especially of the break-up dialogue between Neela and the Australian guy. Just sounded like a disquisition on emotions in the abstract, rather than a conversation between two flesh and blood people who are distraught.) So, what I'm saying - I'm not the only one with problems!
