Attending an annual "Ladies' Luncheon" is an obligatory holiday tradition for some young women, especially if one of the ladies is your mother. Two ladies' lunch veterans are Arline Klatt and Beth Lisick, the writers who created the Porch Light storytelling series In San Francisco. For the two of them, the annual tradition brings mixed feelings -- whether the lunching ladies are wearing sweaters embellished with actual light-up Christmas trees, or smart Chanel suits from the '80s.
