A night out in The Wanderer

The other night I got out of work around 10 and Peter invited me to get some beers with him....he told me he would pick me up in 20 minutes so I was waiting for him at my apartment.....an hour passed by and he was like "What are you doing?" I was like "I thought you were coming to get me?" He said he would be right there. He sounded really weird, but I didn't think anything of it since he can get weird sometimes. He finally called me and said he was waiting by my apartment. I went outside and got in the car and realized he was very drunk. I got pretty nervous because I didn't know what to do and I kept trying to ask him how much he had been drinking. He was slurring his words and when we got to the bar we just hung out in his car for awhile and he was opening up to me about a lot of things that he never talks about like his dad's death. When we got into the bar I got him some water and we talked for a good couple hours....he kept repeating himself and eventually started crying about how he has been such a bad person and all he cares about is his family and he just wants his mother to be proud of him. I felt super bad because I've never seen Peter like this before. I went outside to have a smoke and when I got back inside he was drinking this HUGE beer. I tried to get it away from him but he kept saying "I always do this, I always do this." I just kept distracting him from drinking and asking him a lot of questions. It was eventually last call and I still didn't feel safe with him driving so I didn't know what to do. My apartment was just down the street so I told him he could just stay at my place. We got there and he wouldn't come inside so he drove all the way back home. I felt really freaked out, but somehow he made it back home safely. I just told him that if he ever needs a driver I don't mind because I don't want him to get a DUI, or worse him get hurt or hurt someone else. So I've been pretty worried about him lately. I just hope he doesn't get like that ever again!
