YOU SAID:

I was standing outside my house and witnessed this very strange incident between an extremely inebriated girl and a guy she apparently did not know. I saw them standing up and holding eachother (I thought they were kissing). Then a car comes by, sees it, and stops and asks if everything is okay. This guy is trying to say he didn't know this girl and was just trying to make sure she got home (she couldn't convey where she lived). The people from the car then get the attention of a UCPD car going by and get them to stop and resolve this issue. As the cops were coming, the guy got on his phone and started to walk away. The people from the car that stopped and I started to tell the police that the guy was leaving, and then the police made him stop. They then talked to everyone, and I explained what I saw. The inebriated girl then calls her friend who was supposed to give her a ride, her friend shows up in a car, and then the police act like the matter is finished and everyone starts to disperse, including the guy. The thing is though the inebriated girl's friend that picked her up said she knew the guy who was with her, who the inebriated girl apparently did not know. It was all very strange. Then I walked back inside. (edited)

私は自分の家の外に立って、非常に酔っ少女と、彼女はどうやら知らなかった男との間に、この非常に奇妙な事件を目撃しました。私は彼らが立っと（私は、彼らがキスをしたと思った）お互いを保持して見ました。その後、車はによって来る、それを見て、そして停止し、すべてが正常であるかどうかを尋ねます。この男は、彼がこの少女のANを知らなかったと言うしようとしています
