The Uptight Stoner Couchsurfer

I requested her couch in the morning,and she accepted my request. I got to the city (Sacramento,CA)  at night. I had hitchhiked all the way to the city,and I called her as soon as I arrived and she picked me up.
She was stoned when she picked me up. She was talking gibberish and crossing a couple of red lights, until we got to her place. When we got to her place,the smell of marijuana was very strong but there was no other evidence of drug use. She asked me to go outside and we talked a bit outside about her couchsurfing experiences and her job overseas as an ESL teacher. She was attractive. Her smile reminded me of my beautiful exgirlfriend. A blond with blue eyes and a nice body.
The following night, she invited me for drinks,but the bar nearby was closed. I told her I did not have much money,and she said that would not be a problem,but since the bar was closed we decided to just stop at a grocery store to buy some cheap wine. I told her I smoke pot every now and then and "she said,oh my god,i did not know,I was trying to hide the fact that I smoke pot,but when you got to my place,I knew I you could smell it" yeah big deal, so she told me that we could smoke a joint once we got back to her place.
When we got to her place,she took out a bag of pot and put it on the table with the wine.She asked me what type of music I like. I said to create a station in Pandora with the band Combichrist.I told her it was electronic music. She sat back down on the couch across from the table,and then we started hitting the pipe,and drinking wine. After a while,she said that the music was making her feel weird. I asked her how. She said that it reminded her of being attacked or raped or something to that effect. I laughed and I told her it was just music. I casually mentioned to her that I had read a psychology book about rape. She started talking about rough sex and then interrupted herself and asked me "wait,so what  is your stance on rape?,because I live alone,and you better tell me if you want to countinue staying here" her face changed and she looked very aggressive and told her that i thought rape was wrong but that I believed she was getting too uptight and asked her if we could change the subject.
She said "so what do you want to talk about?" I told her it did not matter and i could not really come up with anything because I was too stoned and a little uncomfortable about she had just said.she got up and was gone for about 15 minutes, and then asked me if I wanted to watch a video with her,it was about this kid called David and how he acted under the influence of thedrugs the dentist had given him.So I was laughing very hard, because the video was awfully funny, but she was not laughing nearly as hard as I was, then I asked her to play it again, and she said "ok but after this I have to go to bed" I told her she could go to bed anytime she wanted to, I just wanted to watch the video again.
So she went to her bedroom and I crashed on the living room couch.
She had let me borrow a backpack that was in really bad shape, I returned it before I left. She sent me a text message saying that her backpack was totally destroyed and that she thought I should replace it but whatever. I told her I would send her a check and she said "I don't want a check,just forget it" and then she went on to say that she felt taken advantage of because hosting had cost her money, no kidding! Hosting does cost money. I don't know if she wanted to be financially compensated or if she just wanted to complain.
One thing I'm sure of,is that this girl had serious emotional problems,on top of that, she was unemployed,so she should not have been hosting,but I bet in her mind she was so great just to let me crash on the couch and did not pay attention of how uncomfortable she made me feel.
