Wig-Wearing Lady, who's been reading a Harlequin romance, just got up from her seat. Is she going to . . . ? She is! She's sitting down next to Long-Haired Sleeping Man! Now she's shaking him awake -- what's the deal? Does she know him? Or is this just another story unfolding in the cozy mystique of our favorite people-watching spot? Observing the many muted mini-dramas unfolding among the after-1 a.m. crowd in dimly lit Terminal Four is among our guiltiest pleasures. There might be only a handful of characters, but that's all it takes. Last time we were there, we watched a sexy bearded guy make a paper pterodactyl for a zombie-like mother and her three noisy kids, witnessed a fight between two polyester-clad flight attendants, and looked on as a sour-faced septuagenarian couple preached the gospel to a panhandler. Settle yourself into a reasonably comfortable black leatherette seat and just ponder and observe. There's a different cast and a different set of stories every night.
