It's weirder in Cambodia because all hope is lost. Not being around even other homeless people that speak English is much more isolating then being destitute in your home country. There is also a meth problem in Cambodia so he was likely living with addicts who were shooting up. Some of the rooms are like shooting galleries with bloody swabs and rags just left on the floor.
We call them "deathpats". It's expats that wash up there to die. Refusing to go home, or can't get themselves together to actually return. They end up as alcoholics or drug addicts, and victims of hookers and pimps or just other people around that can see they are going downhill that rob them of everything when they are high or wasted. It happens in those really cheap rooms where nobody cares.
