I'll start. When I first started living in Portland I was seventeen and had zero cash. I rented a place in a pretty characterful but borderline derelict redbrick with another guy. We both worked at a coffee shop. Anyway, the place was a single room with a moldy fitted carpet. There was a hotplate, two mattresses, and literally nothing else except a stained bathtub in the middle of the room. It was literally an out of place object. The bathtub was actually connected to the mains, so water came out of the faucet. My friend and me would piss in the bathtub, but if we had to drop a load we had to go down two flights of stairs to the restroom the people on that floor shared. These were old, gross, piggy Middle Eastern men and the toilet was the most disgusting place I have ever seen, even counting the fact I grew up in a rural area with outhouses. Once one of the elderly residents actually shit in the sink and clogged it up. We had to plunger the turd out. The old Arab dudes would jerk off without closing the door. There was lice in the wall-to-wall carpet.
I paid ten bucks a week for it in the late 70s. Anyway they day I realized I had to move out when I got back home and there was these two homeless guys fucking against the tub. Later, I found out from my friend that the super was bribed to let them in to fuck because he didn't think nobody was going to be home then. They were old, gross, and smelled rank and they were really going at it noisily, stained jeans around their ankles, skinny hips pumping, yellowed teeth gleaming with spit. I left at roughly the speed of light. I still remember the top hobo not only by his smell (piss, sweat, and malt liquor), but the fact he kept calling the bottom, who looked like he had some kind of elephantiasis in his ankles, 'Betty'. I think hell looks something like that.
After that I slept rough for a couple of weeks before finding a place at the YMCA.
