Stupidity: Billy gave Skylar (a stranger at the diner who did a "dine and dash", not paying $12 for her food) a ride. She came across as suspicious, angry and "street smart." Billy nevertheless put his envelope containing $500 cash between the driver's and front passenger's seat where Skylar could see - and take - it. When they arrived at the Kite Skating site, Billy got out of his Jeep without even thinking about the money. (Skylar gave the money back, but it could have been kept). (00:19:19 - 00:20:35)
