I have a neighbor, a total drunk and completely gone. But he was quiet, never bothered anyone. Just drank. And then one morning, they found him behind the bus stop, completely incapacitated, unable to speak or move (most likely a stroke). They took him to the hospital. It turned out he also had pneumonia. They kept him there for a week and brought him back to his apartment. The man is completely unable to walk. On Friday. None of the neighbors were even informed. Meaning, no one knew he was brought back and left in that mess. Until yesterday, when I accidentally found out from the medic that he was brought back on Friday. Damn it, I immediately realized there was no movement in the apartment at all. I rushed home, went up to his place. Opened the door (luckily it doesn't lock), and couldn't find him among the junk and bottles. I called that medic again, where did they put him? If he can't walk, he couldn't have left. I see a mattress lying between the sofa and the bed. And the thought, he's there. Well, there's no smell of decomposition. I pulled the mattress, and he was indeed there, but already dead. I called the police. They came, and confirmed he had died 4-5 hours ago. So, the man was brought back on Friday and lay there without any help until Wednesday. Is it okay to leave someone incapacitated like that? Honestly, I understand he chose his path, but abandoning him like a dog to die is also pretty messed up. What if it had been a lonely elderly woman who wasn't an alcoholic? Would they have just left her to die too? To perish?
