Wow, you are really going the extra mile to make him at home! Good for you!

I know there are some senior centers that have social activities, like a lunch or something. He'd hardly be the only person there with hearing trouble. In fact, he'd find a sympathetic group, I think.

My experience is that there are plenty of people (women especially) who'd love to talk. They won't drag him off to the altar; they just enjoy having male company. (At one place, my wife had to leave me on my own for a few minutes and I got swarmed. It was flattering; I'm in my 60's and disabled -- not exactly a "chick magnet".)

A senior center near me hosts occasional day trips -- to a museum or event, sometimes even a casino. Very reasonably priced.

Good luck! I hope he makes some new friends.
