Back in high school, I fulfilled my community service requirement at a local nursing home. Several of the residents there had no local friends or family, and as a result, no visitors. I was tasked just with giving them someone to talk to.
What surprised me is that most of the residents did not want to talk to someone - they wanted to be left alone. Many assumed they'd be going home, and didn't want to build any friendships. The one exception who stood out was a man in what I believe was his late 70s, functionally deaf but still able to speak. I'd communicate with him by writing on a whiteboard, and letting him speak in response.
This man over the course of several weeks gave me his life's story - if I recall, he'd worked most of his life as a Boston firefighter. He had quite a bit to say, and I could tell that given the nature of interacting with him, no one else had really spent time talking with him since he'd become deaf. I don't know how long he had been deaf for, but I imagine this wasn't terribly different from being "locked in".
My second to last week at the nursing home, he told me that he'd said everything there was to say - he didn't have any more stories, but was happy to have seen me come back.
My last week there, I went to go see him anyway, only to find the bed clean and his things moved out. It turned out that he had passed away earlier in the week.
I'm happy that I was able to give him those few hours.
