Was that a wink? Is she flirting with me? Man, she seems happy tonight. Maybe she's tipsy. No, I think she's just flirting with me. Viewers of WSVN's nightly newscasts can be excused for wondering if Laurie Jennings is communicating directly with them via the tube. When she began at Channel 7 in February 1998, she was a mechanically rigid human automaton improbably paired with blowhard Rick Sanchez. After the voluble Sanchez split for MSNBC, Jennings began a subtle but noticeable transformation, from straightlaced news reader to emotive broadcaster with personality. Those saucy little winks. The lead-in comments spiced with attitude. A relaxed posture that hinted at seduction. The change has been a bit unsettling, but ultimately it's just what we want and expect in our love-hate relationship with Seven News, the big show.
