When I get really fucked up, I forget how to get to the bathroom sometimes....Once I pissed in the trash can, not bad, and then once after that I nearly did the same thing till Jooles yelled to me that I wasn't in the bathroom yet. She really freaked when I opened the linen closet, till she guided me to the real bathroom...
This has happened to me as well. My first year here, I lived on ASU campus and I started in January. I went back to Virginia for the summer and stayed with my parents, didn't do much drinking. When I came back in August I was matched with a new roommate in the dorm I had never met. I came in like 5 days later than everyone because they were all doing orientation, etc. So I walked into my room, met my new roommate who had been wondering where I was for 5 days, and then a friend of mine from the previous semester came by looking for me. I took off with him, ended up going to a party with a keg and doing beer bongs. I had no tolerance and don't remember going back to my room.
The rest of this is what my roommate, who I had met for all of 5 minutes, told me the next day. I came in wasted and moved my still-packed bags onto the floor, and proceeded to sleep on my bare mattress. At some point I got up and was feeling the wall above his bed. it was roughly the spot where the door to the room at my parents' house would have been. I guess I didn't realize where I was. Eventually I found a shopping bag and started to pee in it. My roommate asked what the fuck I was doing and turned on the light, and then he told me where the bathroom was. Evidently I laughed and said, "Oh yeah." I left the slightly filled bag of pee on the floor. He left the light on thinking I'd clean it up. Instead I went directly back to my bed and passed out.
I never did get along with that guy, I think he was scared of me after that.
