I moved to my neighbourhood a couple of years ago. I'm not in the UK, and I'm learning the language here, am fairly confident, but I'm in no way fluent yet.
I live in a little road where most of us know one another – we say hello and sometimes walk the dogs together.
There's a man in his 60s who lives alone and has always been very sweet and welcoming to me. We don't talk much but he always waves and smiles and we exchange pleasantries from time to time.
About a month ago an ambulance pulled in as I was leaving the house with the dogs, and when I returned I could hear this man shouting at the paramedics. He was clearly fighting them off as they tried to get him out of the house, and sounded very distressed. Another neighbour was leaving their house at the time, and asked me if I'd heard the shouting the night before – apparently this man had been screaming like an animal, so his next-door neighbour had gone to knock on the door and check on him and he'd opened the door wielding a screwdriver, so she left quickly. My neighbour said he often heard him emptying a lot of bottles into the recycling bins and thinks he has a significant alcohol problem.
Early this morning as I left with the dogs there was another ambulance outside and he came out on a stretcher with his face covered in blood and bruises and his arm in a makeshift sling.
I know he has family somewhere but they're not often around, and I just feel awful at the thought of him suffering so significantly on his own.
On the one hand, it's none of my business, and I don't want to get entangled in something potentially dangerous. On the other, he's been so warm to me and I hate the thought of him knowing that I've seen him in these states and not saying or doing anything to help.
What, if anything, could or should I do here?
Keep my nose out and maintain a distance? Acknowledge it with him? Something more?
