Question: Given the following context:  Matt Franklin is a recent MIT graduate who works at a Los Angeles Suncoast Video store in 1988 while trying to figure out what he wants to do with his life, something that his police officer father has grown impatient with. While working one day, Matt's high school crush, Tori Frederking walks into the store. After pretending that he doesn't work there and saying that he works at Goldman Sachs in an effort to impress her, Tori invites Matt to a Labor Day party, hosted by Matt's twin sister Wendy's boyfriend, Kyle Masterson, at his hillside home. Later that night, Matt, Wendy, and Matt's best friend, Barry Nathan, head to the party. On the drive over, Barry steals a brand new Mercedes-Benz convertible from the car dealership he got fired from earlier that day, justifying his actions by saying that Matt needs the convertible if he really wants to impress Tori. The trio arrive at the party. While there, Matt catches up with an old classmate (who actually works at Goldman Sachs) and then awkwardly tries to woo Tori. Barry snorts some cocaine he found in the glove box of the stolen convertible and gets involved in a dance-off, and Wendy's boyfriend proposes to her in front of everyone at the party. She says yes, upsetting Matt, who doesn't think that Kyle will support her in her dream to attend graduate school at the University of Cambridge. Tori eventually invites Matt and Barry to another party her boss is hosting in Beverly Hills. Matt takes Tori there in the Mercedes, while Barry rides with her two friends in another car, using the cocaine as an enticement to let him go along. Barry has a wild sexual encounter with an older woman while Matt and Tori continue to mingle with each other, after Matt's successful 'put down' of Tori's boss, a habitual sexual harasser. They leave the party to go into a neighbor's backyard where they jump on a trampoline, play truth or dare, and end up having sex.  answer the following question:  What's the full name of the person who justifies stealing a car?
Answer:
Barry Nathan
