Secret
It's a good thing that her life has made her adept at the lying she always had a certain natural flair for, because it seems like she's keeping something from almost everyone she knows lately.
She conveniently neglects to mention to Helen and Bob that her recently accquired a roommate that just happens to be their self-declared nemesis and their infant son's would-be kidnapper.
She lets it slip her mind to tell Helen that she's sold the apartment, and that she and the aforementioned "roomie" are right in the middle of packing to move to this nice, rundown little cottage a few miles from the city.
She very, very carefully doesn't mention to Buddy that she has at least weekly contact with the Parrs.
Never for a moment does it occur to her to get everything out in the open, or that lying is lying, and what she calls a wilful exclusion of the truth is lying, and lying almost always ends up making a mess.
