Task: Question Answering
Input (English): Passage: The story is narrated from the perspective of aspiring furniture designer Vanessa Walling, (Shawkat) whose plan to stay at home for a few months after college has turned into years.  She makes up increasingly stupid reasons why she does not like all the apartments that her mother and colleagues find online for her.
She witnesses the heartache between her parents, David and Paige Walling, (Laurie and Keener) as their relationship falls apart from years from sleeping in separate beds and pretending to be happy. Their best friends, Terry and Cathy Ostroff, (Platt and Janney) live across the street in their suburb of West Orange, New Jersey. The friendship between the two men is so predictable you could "set your clock by it". This all changes, however, when prodigal 24-year-old daughter, Nina Ostroff, (Meester), returns from a 5 year absence after her fiance, Ethan, disliked by her parents, dumped her. 
Nina and Vanessa had been childhood best friends before Nina moved on to new friends during high school, and Vanessa is unhappy to see her back. However, both sets of families (at least the mothers) would like to see newly-single Nina and jet-setting son Toby Walling form a relationship, and Cathy is excited when the Toby and Nina go to the basement together after their Thanksgiving meal. Despite flirtatious back-and-forth, Toby falls asleep after drinking, leaving Nina alone in the house. She goes to find David in the pool house where he said he was watching "late night TV", and they sit together briefly, watching a Korean basketball game. There is a chemistry between them, and they share a kiss before David pulls away. 
Question: What is the full name of the mother of the aspiring furniture designer's childhood best friend?
Output (English): Cathy Ostroff.
