LOS ANGELES (AP) – Just as Don Draper becomes more aware of his mortality, Matthew Weiner is very aware that “Mad Men’s” days are numbered. Weiner is the creator and head writer of the show. Sunday’s episode is not only the last one of season six, it has to set up the final season of the series. But Weiner says he didn’t worry about any of that. He says it’ll be like all the other season finales because he writes them as if they’re the last episodes of the series anyway.
