Could you share an hour a week with Sérgio?

I'm writing for my neighbor Sérgio, who's 72. Sérgio lives alone in Recife, and lost a spouse of many years last year. The nearest family lives a long flight away. Sérgio loves local history, and would enjoy someone to chat with. An hour a week, perhaps on Wednesday afternoon, would mean the world. We can also arrange a phone call if you can't visit in person. All visitors will be introduced by me and I'll be there at the first meeting. I'll share references and, if you'd like, a short orientation from the local befriending charity. No special skills are needed - just kindness and patience. Thank you for reading my story.
